Exodus 34:23

You shall redeem the firstborn of a donkey with a lamb. If you will not redeem it, then you shall break its neck. You shall redeem all the firstborn of your sons. No one shall appear before me empty.

“Six days you shall work, but on the seventh day you shall rest: in plowing time and in harvest you shall rest.

“You shall observe the feast of weeks with the first fruits of wheat harvest, and the feast of harvest at the year’s end.

For I will drive out nations before you and enlarge your borders; neither shall any man desire your land when you go up to appear before the LORD, your God, three times in the year.

“You shall not offer the blood of my sacrifice with leavened bread. The sacrifice of the feast of the Passover shall not be left to the morning.

“You shall bring the first of the first fruits of your ground to the house of the LORD your God.

“You shall not boil a young goat in its mother’s milk.”
