Exodus 34:18-28

18— The feast of the unleavened bread shalt thou keep: seven days shalt thou eat unleavened bread, as I have commanded thee, at the appointed time of the month Abib; for in the month Abib thou camest out from Egypt.

19— All that openeth the womb [is] mine; and all the cattle that is born a male, the firstling of ox and sheep.

20But the firstling of an ass thou shalt ransom with a lamb; and if thou ransom [it] not, then shalt thou break its neck. All the first-born of thy sons thou shalt ransom; and none shall appear before me empty.

21— Six days shalt thou work, but on the seventh day thou shalt rest; in ploughing time and in harvest thou shalt rest.

22— And thou shalt observe the feast of weeks, of the first-fruits of wheat-harvest, and the feast of ingathering at the turn of the year.

23Thrice in the year shall all thy males appear before the Lord Jehovah, the 1God of Israel.

24For I will dispossess the nations before thee, and enlarge thy border, and no man shall desire thy land, when thou goest up to appear before the face of Jehovah thy 2God thrice in the year.

25— Thou shalt not offer the blood of my sacrifice with leaven; neither shall the sacrifice of the feast of the passover be left over night until the morning.

26— The first of the first-fruits of thy land shalt thou bring into the house of Jehovah thy 3God. Thou shalt not boil a kid in its mother's milk.

27And Jehovah said to Moses, Write thee these words; for after the tenor of these words have I made a covenant with thee and with Israel.

28— And he was there with Jehovah forty days and forty nights; he ate no bread, and drank no water. — And he wrote on the tables the words of the covenant, the ten words.
