Commentaries
16:1-17 The laws for the three yearly feasts are here repeated; that of the Passover, that of the Pentecost, that of Tabernacles; and the general law concerning the people's attendance. Never should a believer forget his low estate of guilt and misery, his deliverance, and the price it cost the Redeemer; that gratitude and joy in the Lord may be mingled with sorrow for sin, and patience under the tribulations in his way to the kingdom of heaven. They must rejoice in their receivings from God, and in their returns of service and sacrifice to him; our duty must be our delight, as well as our enjoyment. If those who were under the law must rejoice before God, much more we that are under the grace of the gospel; which makes it our duty to rejoice evermore, to rejoice in the Lord always. When we rejoice in God ourselves, we should do what we can to assist others also to rejoice in him, by comforting the mourners, and supplying those who are in want. All who make God their joy, may rejoice in hope, for He is faithful that has promised.
13-17. Thou shalt observe the feast of tabernacles seven days—(See on [147]Ex 23:14; [148]Le 23:34; [149]Nu 29:12). Various conjectures have been formed to account for the appointment of this feast at the conclusion of the whole harvest. Some imagine that it was designed to remind the Israelites of the time when they had no cornfields to reap but were daily supplied with manna; others think that it suited the convenience of the people better than any other period of the year for dwelling in booths; others that it was the time of Moses' second descent from the mount; while a fourth class are of opinion that this feast was fixed to the time of the year when the Word was made flesh and dwelt—literally, "tabernacled"—among us (Joh 1:14), Christ being actually born at that season.
