Exodus 13:10-12

American Standard Version

¹⁰ Thou shalt therefore keep this ordinance in its season from year to year.

¹¹ And it shall be, when Jehovah shall bring thee into the land of the Canaanite, as he sware unto thee and to thy fathers, and shall give it thee, ¹² that thou shalt ^[a]set apart unto Jehovah all that openeth the womb, and every firstling which thou hast that cometh of a beast; the males shall be Jehovah’s.
