Deuteronomy 25:4-6

Wycliffe Bible

⁴ Thou shalt not bind the mouth of the ox treading (out) thy fruits in the cornfloor. (Thou shalt not bind the mouth of the ox threshing thy grains on the threshing floor.)

⁵ When brethren dwell together, and one of them is dead without free children, the wife of the dead brother shall not be wedded to another man, but his brother shall take her, and he shall raise (up) the seed of his brother.

⁶ And he shall call her first begotten son by his name, that is, of the dead brother, (so) that his name be not done away from Israel.
