Genesis 21:1

⁶The LORD’s words are flawless words, as silver refined in a clay furnace, purified seven times.

¹⁰He said, “I will certainly return to you at about this time next year; and behold, Sarah your wife will have a son.” Sarah heard in the tent door, which was behind him.

¹⁴Is anything too hard for the LORD? At the set time I will return to you, when the season comes around, and Sarah will have a son.”

¹⁹God said, “No, but Sarah, your wife, will bear you a son. You shall call his name Isaac.^[+] I will establish my covenant with him for an everlasting covenant for his offspring after him.

²³However, the son by the servant was born according to the flesh, but the son by the free woman was born through promise.

²¹The LORD visited Hannah, and she conceived and bore three sons and two daughters. The child Samuel grew before the LORD.

³⁵Heaven and earth will pass away, but my words will not pass away.

²in hope of eternal life, which God, who can’t lie, promised before time began;

⁶Then she arose with her daughters-in-law, that she might return from the country of Moab; for she had heard in the country of Moab how the LORD ^[+] had visited his people in giving them bread.

²⁸Now we, brothers, as Isaac was, are children of promise.
