In the fourteenth day of this month, at twilight, you are to observe it at its appointed time; you must keep it in accordance with all its statutes and all its customs.”

They must not leave any of it until morning, nor break any of its bones; they must observe it in accordance with every statute of the Passover.

(30:1) So Moses told the Israelites everything, just as the Lord had commanded him.

So the Israelites did according to all that the Lord commanded Moses; that is the way they camped under their standards, and that is the way they traveled, each with his clan and family.

So Moses and Aaron and the entire community of the Israelites did this with the Levites. According to all that the Lord commanded Moses concerning the Levites, this is what the Israelites did with them.

And they observed the Passover on the fourteenth day of the first month at twilight in the wilderness of Sinai; in accordance with all that the Lord had commanded Moses, so the Israelites did.

If a man makes a vow to the Lord or takes an oath of binding obligation on himself, he must not break his word, but must do whatever he has promised.
