Exodus 13:10-12

Darby Translation

¹⁰ And thou shalt keep this ordinance at its set time from year to year.

¹¹ And it shall be when Jehovah hath brought thee into the land of the Canaanites, as he hath sworn to thee and to thy fathers, and hath given it thee,

¹² that thou shalt offer unto Jehovah all that breaketh open the womb, and every firstling that cometh of cattle which is thine: the males [shall be] Jehovah's.
