19. All that openeth the womb is mine; and all thy cattle that is male, the firstlings of ox and sheep.
20. And the firstling of an ass thou shalt redeem with a lamb: and if thou wilt not redeem it, then thou shalt break its neck. All the firstborn of thy sons thou shalt redeem. And none shall appear before me empty.
21. Six days thou shalt work, but on the seventh day thou shalt rest: in plowing time and in harvest thou shalt rest.
