Exodus 34:20-22

Darby Translation

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.

²² —And thou shalt observe the feast of weeks, of the first-fruits of wheat-harvest, and the feast of ingathering at the turn of the year.
