Devarim 25:4-6

Orthodox Jewish Bible

⁴ Thou shalt not muzzle the shor when he treadeth out the grain [1C 9:9; 1Ti 5:18].

⁵ If achim dwell together, and one of them die, and ben ain lo (have no child), the eshet hamet (wife of the dead) shall not marry outside unto an ish zar (strange man); her yevam (deceased husband’s brother) shall go in unto her, and take her to him as a wife, and perform the levirate marriage.

⁶ And it shall be, that the bechor which she beareth shall succeed in the shem of his brother which is dead, that shmo be not blotted out from Yisroel [see Ruth].
