13 "You must observe the Festival of Shelters for seven days at the end of the harvest season, after the grain has been threshed and the grapes have been pressed. 14 This festival will be a happy time of celebrating with your sons and daughters, your male and female servants, and the Levites, foreigners, orphans, and widows from your towns. 15 For seven days you must celebrate this festival to honor the Lord your God at the place he chooses, for it is he who blesses you with bountiful harvests and gives you success in all your work. This festival will be a time of great joy for all. 16 "Each year every man in Israel must celebrate these three festivals: the Festival of Unleavened Bread, the Festival of Harvest, and the Festival of Shelters. On each of these occasions, all men must appear before the Lord your God at the place he chooses, but they must not appear before the Lord without a gift for him. 17 All must give as they are able, according to the blessings given to them by the Lord your God.
Matthew Henry's Commentary on Deuteronomy 16:13-17
Commentary on Deuteronomy 16:1-17
(Read Deuteronomy 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.
