Genesis 20:13

Abraham's deceit was not just a brief loss of faith. Even after being scolded in Egypt, he used this strategy everywhere he traveled (compare 12:12–13). Living by faith requires perseverance.

• This second "sister story" in Genesis (compare 12:10–20) happened just before Sarah became pregnant with Isaac (chapter 21). In both instances, God protected Abraham and Sarah's marriage to keep it pure for the covenant promises. To be part of God's plan, his people must separate from worldly corruption.

• This story happened in the promised land. It showed Israel how God intervened in people's lives to fulfill his plan. He protected them from threats from other tribes. He used his chosen people to mediate his relationship with other nations.

• By preventing adultery from destroying Abraham's marriage, God reminded the Israelites not to marry those who would lead them away from the Lord (Ezra 9:1–4; Nehemiah 13:23–27; Malachi 2:10–17). They should not allow any chance for temptation. Adultery would eventually destroy the covenant and the people.

yet indeed she is my sister--(See on Gen 11:31). What a poor defense Abraham made. The statement absolved him from the charge of direct and absolute falsehood, but he had told a moral untruth because there was an intention to deceive (compare Gen 12:11-13). "Honesty is always the best policy." Abraham's life would have been as well protected without the fraud as with it: and what shame to himself, what distrust to God, what dishonor to religion might have been prevented! "Let us speak truth every man to his neighbor" [Zac 8:16; Eph 4:25].




Next: Genesis Chapter 21

Abimelech, being thus warned of God in a dream, takes the warning, and, as one truly afraid of sin and its consequences, he rises early to obey the directions given him.
I. He has a caution for his servants, Gen 20:8. Abraham himself could not be more careful than he was to command his household in this matter. Note, Those whom God has convinced of sin and danger ought to tell others what God has done for their souls, that they also may be awakened and brought to a like holy fear.
II. He has a chiding for Abraham. Observe,
1. The serious reproof which Abimelech gave to Abraham, Gen 20:9, Gen 20:10. His reasoning with Abraham upon this occasion was very strong, and yet very mild. Nothing could be said better; he does not reproach him, nor insult over him, does not say, "Is this your profession? I see, though you will not swear, you will lie. If these be prophets, I will beg to be freed from the sight of them:" but he fairly represents the injury Abraham had done him, and calmly signifies his resentment of it. (1.) He calls that sin which he now found he had been in danger of a great sin. Note, Even the light of nature teaches men that the sin of adultery is a very great sin: be it observed, to the shame of many who call themselves Christians, and yet make a light matter of it. (2.) He looks upon it that both himself and his kingdom would have been exposed to the wrath of God if he had been guilty of this sin, though ignorantly. Note, The sins of kings often prove the plagues of kingdoms; rulers should therefore, for their people's sake, dread sin. (3.) He charges Abraham with doing that which was not justifiable, in disowning his marriage. This he speaks of justly, and yet tenderly; he does not call him a liar and cheat, but tells him he had done deeds that ought not to be done. Note, Equivocation and dissimulation, however they may be palliated, are very bad things, and by no means to be admitted in any case. (4.) He takes it as a very great injury to himself and his family that Abraham had thus exposed them to sin: "What have I offended thee? If I had been thy worst enemy, thou couldst not have done me a worse turn, nor taken a more effectual course to be revenged on me." Note, We ought to reckon that those do us the greatest unkindness in the world that any way tempt us or expose us to sin, though they may pretend friendship, and offer that which is grateful enough to corrupt nature. (5.) He challenges him to assign a cause for his suspecting them as a dangerous people for an honest man to live among: "What sawest thou, that thou hast done this thing? Gen 20:10. What reason hadst thou to think that if we had known her to be thy wife thou wouldst have been exposed to any danger by it?" Note, A suspicion of our goodness is justly reckoned a greater affront than a slight upon our greatness.
2. The poor excuse that Abraham made for himself.
(1.) He pleaded the bad opinion he had of the place, Gen 20:11. He thought within himself (though he could not give any good reason for his thinking so), "Surely the fear of God is not in this place, and then they will slay me." [1.] Little good is to be expected where no fear of God is. See Psa 36:1. [2.] There are many places and persons that have more of the fear of God in them than we think they have: perhaps they are not called by our dividing name, they do not wear our badges, they do not tie themselves to that which we have an opinion of; and therefore we conclude they have not the fear of God in their hearts, which is very injurious both of Christ and Christians, and makes us obnoxious to God's judgment, Mat 7:1. [3.] Uncharitableness and censoriousness are sins that are the cause of many other sins. When men have once persuaded themselves concerning such and such that they have not the fear of God, they think this will justify them in the most unjust and unchristian practices towards them. Men would not do ill if they did not first think ill.
(2.) He excused it from the guilt of a downright lie by making it out that, in a sense, she was his sister, Gen 20:12. Some think she was own sister to Lot, who is called his brother Lot (Gen 14:16), though he was his nephew; so Sarah is called his sister. But those to whom he said, She is my sister, understood that she was so his sister as not to be capable of being his wife; so that it was an equivocation, with an intent to deceive.
(3.) He clears himself from the imputation of an affront designed to Abimelech in it by alleging that it had been his practice before, according to an agreement between him and his wife, when they first became sojourners (Gen 20:13): "When God caused me to wander from my father's house, then we settled this matter." Note, [1.] God is to be acknowledged in all our wanderings. [2.] Those that travel abroad, and converse much with strangers, as they have need of the wisdom of the serpent, so it is requisite that that wisdom be ever tempered with the innocence of the dove. It may, for aught I know, be suggested that God denied to Abraham to punish them for this sinful compact if they will not own their marriage, why should God own it? But we may suppose that, after this reproof which Abimelech gave them, they agreed never to do so again, and then presently we read (Gen 21:1, Gen 21:2) that Sarah conceived.

When God caused me to wander [430] Because the verb is here put in the plural number, I freely expound the passage as referring to the angels, who led Abraham through his various wanderings. Some, with too much subtlety, infer from it a Trinity of Persons: as if it had been written: The gods caused me to wander. I grant, indeed, that the noun 'lhym (Elohim,) is frequently taken for God in the Scripture: but then the verb with which it is connected is always singular. Wherever a plural verb is added then it signifies angels or princes. [431] There are those who think that Abraham, because he was speaking with one who was not rightly instructed, spoke thus in conformity with the common custom of the heathen; but, in my opinion, most erroneously. For to what purpose did he, by erecting altars, make it manifest that he was devoted to the service of the only true God, if it were lawful for him afterwards to deny, in words, the very God whom he had worshipped? On which subject we have before spoken, as the case required. Abraham, however, does not complain respecting, the angels, that he had been led astray by their fallacious guidance: but he points out what his own condition formerly was; namely, that having left his own country, he had not only migrated into a distant land, but had been constantly compelled to change his abode. Wherefore there is no wonder, that necessity drove him into new designs. Should any one inquire, why he makes angels the guides of his pilgrimage? the answer is ready; Although Abraham knew that he was wandering by the will and providence of God alone, he yet refers to angels, who, as he elsewhere acknowledges, were given him to be the guides of his journey. The sum of the address is of this tendency; to teach Abimelech, that Abraham was alike free from malicious cunning, and from falsehood: and then, that because he was passing a wandering and unquiet life; Sarah, by agreement, had always said the same thing which she had done in Gerar. This wretched anxiety of the holy man might so move Abimelech to compassion as to cause his anger to cease.

When God caused me to wander - Here the word אלהים Elohim is used with a plural verb, (התעו hithu, caused me to wander), which is not very usual in the Hebrew language, as this plural noun is generally joined with verbs in the singular number. Because there is a departure from the general mode in this instance, some have contended that the word Elohim signifies princes in this place, and suppose it to refer to those in Chaldea, who expelled Abraham because he would not worship the fire; but the best critics, and with them the Jews, allow that Elohim here signifies the true God. Abraham probably refers to his first call.

And it came to pass, when God caused me to wander from my father's house,.... In Ur of the Chaldees, from whence God called him to go forth; which laid him under an obligation to depart from thence, and move from place to place, and go he knew not where, as in Hebrews 11:8; or "the Gods", as it is in the plural number, and so the verb in construction with it; not the idol gods, the gods of the Gentiles, as the Targum of Jonathan, who interprets the words thus,"and it was when the worshippers of idols sought to cause men to err, and I went from my father's house;''but the true God, as Jarchi, Aben Ezra, and Ben Melech acknowledge, and is by many Christian interpreters understood of the three Persons in the Godhead:

that I said unto her, this is thy kindness which thou shalt show unto me; this I shall take as a favour done me, as an instance of tender affection unto me:

at every place whither we shall come, say of me; or for the sake of me, as Aben Ezra and Kimchi, in order to save me from the hands of wicked men, whom he feared would slay him for her sake:

he is my brother; and so he hoped, instead of being ill used, he should meet with favour and friendship on her account, being thus nearly related to her: this he observes to Abimelech, to show that this was an old agreement, near thirty years ago, when they first set out on their travels, and was no new device and scheme which they pursued on account of him and his people in particular; but what they had formerly agreed upon should be said in all places wherever they came, and therefore there was no intention to affront Abimelech; only it supposed they might come into places where wicked men dwelt.

To wander. This word he useth because God did not direct him to any certain place, but sent him out he knew not whither, . And being to travel and sojourn amongst persons of divers tempers and manners, and all pagans, he thought this equivocal expression convenient for his security.

"What sawest thou," i.e., what hadst thou in thine eye, with thine act (thy false statement)? Abimelech did this publicly in the presence of his servants, partly for his own justification in the sight of his dependents, and partly to put Abraham to shame. The latter had but two weak excuses: (1) that he supposed there was no fear of God at all in the land, and trembled for his life because of his wife; and (2) that when he left his father's house, he had arranged with his wife that in every foreign place she was to call herself his sister, as she really was his half-sister. On the subject of his emigration, he expressed himself indefinitely and with reserve, accommodating himself to the polytheistic standpoint of the Philistine king: "when God (or the gods, Elohim) caused me to wander," i.e., led me to commence an unsettled life in a foreign land; and saying nothing about Jehovah, and the object of his wandering as revealed by Him.
