Shemot 13:11-13

Orthodox Jewish Bible

¹¹ And it shall be when Hashem shall bring thee into the land of the Kena’ani, as He swore unto thee and to thy avot, and shall give it thee,

¹² That thou shalt set apart unto Hashem all that openeth the rechem (womb), and every firstling that is born of a behemah which thou hast; hazecharim (the males) shall be Hashem’s.

¹³ And every firstling of a he-donkey thou shalt redeem with a seh; and if thou wilt not redeem it, then thou shalt break its neck; and kol bechor adam among thy banim shalt thou redeem.
