161 Observe the month of Abib by celebrating the Passover to God, your God. It was in the month of Abib that God, your God, delivered you by night from Egypt. 2 Offer the Passover-Sacrifice to God, your God, at the place God chooses to be worshiped by establishing his name there. 3 Don't eat yeast bread with it; for seven days eat it with unraised bread, hard-times bread, because you left Egypt in a hurry - that bread will keep the memory fresh of how you left Egypt for as long as you live. 4 There is to be no sign of yeast anywhere for seven days. And don't let any of the meat that you sacrifice in the evening be left over until morning. 5 Don't sacrifice the Passover in any of the towns that God, your God, gives you 6 other than the one God, your God, designates for worship; there and there only you will offer the Passover-Sacrifice at evening as the sun goes down, marking the time that you left Egypt.

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.
