Exodus 34:19-21

Darby Translation

¹⁹ —All that openeth the womb [is] mine; and all the cattle that is born a male, the firstling of ox and sheep.

²⁰ But the firstling of an ass thou shalt ransom with a lamb; and if thou ransom [it] not, then shalt thou break its neck. All the first-born of thy sons thou shalt ransom; and none shall appear before me empty.

²¹ —Six days shalt thou work, but on the seventh day thou shalt rest; in ploughing time and in harvest thou shalt rest.
