161 "Observe the month of Abib and keep the Passover to the Lord your God, for in the month of Abib the Lord your God brought you out of Egypt by night. 2 And you shall offer the Passover sacrifice to the Lord your God, from the flock or the herd, at the place that the Lord will choose, to make his name dwell there. 3 You shall eat no leavened bread with it. Seven days you shall eat it with unleavened bread, the bread of affliction--for you came out of the land of Egypt in haste--that all the days of your life you may remember the day when you came out of the land of Egypt. 4 No leaven shall be seen with you in all your territory for seven days, nor shall any of the flesh that you sacrifice on the evening of the first day remain all night until morning. 5 You may not offer the Passover sacrifice within any of your towns that the Lord your God is giving you, 6 but at the place that the Lord your God will choose, to make his name dwell in it, there you shall offer the Passover sacrifice, in the evening at sunset, at the time you came out of 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.
