Leviticus 23:23

thou shalt not make clean riddance of the corners of thy field when thou reapest, &c.--(See on Lev 19:9). The repetition of this law here probably arose from the priests reminding the people, at the presentation of the first-fruits, to unite piety to God with charity to the poor.

Here is, I. The institution of the feast of trumpets, on the first day of the seventh month, Lev 23:24, Lev 23:25. That which was now the seventh month had been reckoned the first month, and the year of jubilee was still to begin with this month (Lev 25:8), so that this was their new year's day. It was to be as their other yearly sabbaths, a day of holy rest - You shall do no servile work therein; and a day of holy work - You shall offer an offering to the Lord; concerning these particular directions were afterwards given, Num 29:1. That which is here made peculiar to this festival is that it was a memorial of blowing of trumpets. They blew the trumpet every new moon (Psa 81:3), but in the new moon of the seventh month it was to be done with more than ordinary solemnity; for they began to blow at sun-rise and continued till sun-set. Now, 1. This is here said to be a memorial, perhaps of the sound of the trumpet upon mount Sinai when the law was given, which must never be forgotten. Some think that it was a memorial of the creation of the world, which is supposed to have been in autumn; for which reason this was, till now, the first month. The mighty word by which God made the world is called the voice of his thunder (Psa 104:7); fitly therefore was it commemorated by blowing of trumpets, or a memorial of shouting, as the Chaldee renders it; for, when the foundations of the earth were fastened, all the sons of God shouted for joy, Job 38:6, Job 38:7. 2. The Jewish writers suppose it to have a spiritual signification. Now at the beginning of the year they were called by this sound of trumpet to shake off their spiritual drowsiness, to search and try their ways, and to amend them: the day of atonement was the ninth day after this; and thus they were awakened to prepare for that day, by sincere and serious repentance, that it might be indeed to them a day of atonement. And they say, "The devout Jews exercised themselves more in good works between the feast of trumpets and the day of expiation than at any other time of the year." 3. It was typical of the preaching of the gospel, by which joyful sound souls were to be called in to serve God and keep a spiritual feast to him. The conversion of the nations to the faith of Christ is said to be by the blowing of a great trumpet, Isa 27:13.
II. A repetition of the law of the day of atonement, that is, so much of it as concerned the people. 1. They must on this day rest from all manner of work, and not only from servile works as on other annual festivals; it must be as strict a rest as that of the weekly sabbath, Lev 23:28, Lev 23:30, Lev 23:31. The reason is: For it is a day of atonement. Note, The humbling of our souls for sin, and the making of our peace with God, is work that requires the whole man, and the closest application of mind imaginable, and all little enough. He that would do the work of a day of atonement in its day, as it should be done, had need lay aside the thoughts of every thing else. On that day God spoke peace unto his people, and unto his saints; and therefore they must lay aside all their worldly business, that they might the more clearly and the more reverently hear that voice of joy and gladness. Fasting days should be days of rest. 2. They must afflict their souls, and this upon pain of being cut off by the hand of God, Lev 23:27, Lev 23:29, Lev 23:32. They must mortify the body, and deny the appetites of it, in token of their sorrow for the sins they had committed, and the mortifying of their indwelling corruptions. Every soul must be afflicted, because every soul was polluted, and guilty before God; while none have fulfilled the law of innocency none are exempt from the law of repentance, besides that every man must sigh and cry for the abominations of the land. 3. The entire day must be observed: From even to even you shall afflict your souls (Lev 23:32), that is, "You shall begin your fast, and the expressions of your humiliation, in the ninth day of the month at even." They were to leave off all their worldly labour, and compose themselves to the work of the day approaching, some time before sun-set on the ninth day, and not to take any food (except children and sick people) till after sun-set on the tenth day. Note, The eves of solemn days ought to be employed in solemn preparation. When work for God and our souls is to be done, we should not straiten ourselves in time for the doing of it; for how can we spend our time better? Of this sabbath the rule here given is to be understood: From even unto even shall you celebrate your sabbath.

Leviticus 23:22

22. And when ye reap the harvest of your land, thou shalt not make clean riddance of the corners of thy field when thou reapest, neither shalt thou gather any gleaning of thy harvest; thou shalt leave them unto the poor, and to the stranger: I am the Lord your God.

22. Quum metetis messem regionis vestrae, non absolves usque ad angulum agri tui: nec collectionem messis tuae colliges: pauperi et peregrino relinques eam: Ego Jehova Deus vester.

Neither shalt thou gather any gleaning - See the note on Lev 19:9.

And the Lord spake unto Moses,.... At the same time, in a continued discourse, concerning some other days, which were to be observed in a sacred manner:

saying; as follows.

On the first day of the seventh month there was to be shabbathon, rest, i.e., a day of rest (see Exo 16:23), a memorial of blowing of trumpets, a holy convocation, the suspension of laborious work, and the offering of a firing for Jehovah, which are still more minutely described in the calendar of festal sacrifices in Num 29:2-6. תּרוּעה, a joyful noise, from רוּע to make a noise, is used in Lev 23:24 for שׁופר תּרוּעה, a blast of trumpets. On this day the shophar was to be blown, a blast of trumpets to be appointed for a memorial before Jehovah (Num 10:10), i.e., to call the congregation into remembrance before Jehovah, that He might turn towards it His favour and grace (see at Exo 28:12, Exo 28:29; Exo 30:16); and from this the feast-day is called the day of the trumpet-blast (Num 19:1). Shophar, a trumpet, was a large horn which produced a dull, far-reaching tone. Buccina pastoralis est et cornu recurvo efficitur, unde et proprie hebraice sophar, graece κερατίνη appellatur (Jerome on Hos. Lev 5:8).
(Note: The word תּרוּעה is also used in Num 10:5-6 to denote the blowing with the silver trumpets; but there seems to be no ground for supposing these trumpets to be intended here, not only because of the analogy between the seventh day of the new moon as a jubilee day and the jubilee year (Lev 25:9-10), but also because the silver trumpets are assigned to a different purpose in Num 10:2-10, and their use is restricted to the blowing at the offering of the burnt-offerings on the feast-days and new moons. To this we have to add the Jewish tradition, which favours with perfect unanimity the practice of blowing with horns (the horns of animals).)
The seventh month of the year, like the seventh day of the week, was consecrated as a Sabbath or sabbatical month, by a holy convocation and the suspension of labour, which were to distinguish the first day of the seventh month from the beginning of the other months or the other new moon days throughout the year. For the whole month was sanctified in the first day, as the beginning or head of the month; and by the sabbatical observance of the commencement, the whole course of the month was raised to a Sabbath. This was enjoined, not merely because it was the seventh month, but because the seventh month was to secure to the congregation the complete atonement for all its sins, and the wiping away of all the uncleannesses which separated it from its God, viz., on the day of atonement, which fell within this month, and to bring it a foretaste of the blessedness of life in fellowship with the Lord, viz., in the feast of Tabernacles, which commenced five days afterwards. This significant character of the seventh month was indicated by the trumpet-blast, by which the congregation presented the memorial of itself loudly and strongly before Jehovah on the first day of the month, that He might bestow upon them the promised blessings of His grace, for the realization of His covenant. The trumpet-blast on this day was a prelude of the trumpet-blast with which the commencement of the year of jubilee was proclaimed to the whole nation, on the day of atonement of every seventh sabbatical year, that great year of grace under the old covenant (Lev 25:9); just as the seventh month in general formed the link between the weekly Sabbath and the sabbatical and jubilee years, and corresponded as a Sabbath month to the year of jubilee rather than the sabbatical year, which had its prelude in the weekly Sabbath-day.
