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.

5, 6. Thou mayest not sacrifice the passover within any of thy gates—The passover was to be observed nowhere but in the court of the tabernacle or temple, as it was not a religious feast or sacramental occasion merely, but an actual sacrifice (Ex 12:27; 23:18; 34:25). The blood had to be sprinkled on the altar and in the place where the true Passover was afterwards to be sacrificed for us "at even, at the going down of the sun"—literally, "between the evenings."
