12
Behold, I have taken the Levites from the midst of the children of Israel, instead of every male that opens the womb from among the children of Israel: they shall be their ransom, and the Levites shall be mine.
13
For every first-born mine; in the day in which I smote every first-born in the land of Egypt, I sanctified to myself every first-born in Israel: both of man and beast, they shall be mine: I the Lord.
14
And the Lord spoke to Moses in the wilderness of Sina, saying,
15
Take the number of the sons of Levi, according to the houses of their families, according to their divisions; number ye them every male from a month old and upwards.
16
And Moses and Aaron numbered them by the word of the Lord, as the Lord commanded them.
