Numbers 3:13-15

Wycliffe Bible

¹³ for each first engendered (male) thing is mine; since the time I smote the first engendered (male) thing in the land of Egypt, I have hallowed to me whatever (male) thing is born first in Israel (I have consecrated to myself whatever male is first-born in Israel); from man unto beast they be mine; I am the Lord.

¹⁴ And the Lord spake to Moses in the desert of Sinai, and said,

¹⁵ Number thou the sons of Levi by their fathers’ houses, and by their families, each male from one month and above (every male one month of age and older).
