Verses 17-26 “17Thou shalt make thee no molten gods.
18The feast of unleavened bread shalt thou keep. Seven days thou shalt eat unleavened bread, as I commanded thee, in the time of the month Abib: for in the month Abib thou camest out from Egypt.
19All that openeth the matrix is mine; and every firstling among thy cattle, whether ox or sheep, that is male.
20But the firstling of an ass thou shalt redeem with a lamb: and if thou redeem him not, then shalt thou break his neck. All the firstborn of thy sons thou shalt redeem. And none shall appear before me empty.
21Six days thou shalt work, but on the seventh day thou shalt rest: in earing time and in harvest thou shalt rest.
22And thou shalt observe the feast of weeks, of the firstfruits of wheat harvest, and the feast of ingathering at the year’s end.
23Thrice in the year shall all your menchildren appear before the LORD God, the God of Israel.
24For I will cast out the nations before thee, and enlarge thy borders: neither shall any man desire thy land, when thou shalt go up to appear before the LORD thy God thrice in the year.
25Thou shalt not offer the blood of my sacrifice with leaven; neither shall the sacrifice of the feast of the passover be left unto the morning.
26The first of the firstfruits of thy land thou shalt bring unto the house of the LORD thy God. Thou shalt not seethe a kid in his mother’s milk.”

God gave to Israel plenty of holidays and special procedures in the ceremonial law. The purpose of these special days and activities was that Israel would not forget the Lord. Remember Him! Remember Him! Remember Him! That is what He wants us to do today.
