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.

2. Thou shalt therefore sacrifice the passover—not the paschal lamb, which was strictly and properly the passover. The whole solemnity is here meant, as is evident from the mention of the additional victims that required to be offered on the subsequent days of the feast (Nu 28:18, 19; 2Ch 35:8, 9), and from the allusion to the continued use of unleavened bread for seven days, whereas the passover itself was to be eaten at once. The words before us are equivalent to "thou shalt observe the feast of the passover."
