Deuteronomy 25:5
Context25:5 If brothers live together and one of them dies without having a son, the dead man’s wife must not remarry someone outside the family. Instead, her late husband’s brother must go to her, marry her, 1 and perform the duty of a brother-in-law. 2
Deuteronomy 33:17
Context33:17 May the firstborn of his bull bring him honor,
and may his horns be those of a wild ox;
with them may he gore all peoples,
all the far reaches of the earth.
They are the ten thousands of Ephraim, 3
and they are the thousands of Manasseh.


[25:5] 1 tn Heb “take her as wife”; NRSV “taking her in marriage.”
[25:5] 2 sn This is the so-called “levirate” custom (from the Latin term levir, “brother-in-law”), an ancient provision whereby a man who died without male descendants to carry on his name could have a son by proxy, that is, through a surviving brother who would marry his widow and whose first son would then be attributed to the brother who had died. This is the only reference to this practice in an OT legal text but it is illustrated in the story of Judah and his sons (Gen 38) and possibly in the account of Ruth and Boaz (Ruth 2:8; 3:12; 4:6).
[33:17] 3 sn Ephraim and Manasseh were the sons of Joseph who became founders of the two tribes into which Joseph’s descendants were split (Gen 48:19-20). Jacob’s blessing granted favored status to Ephraim; this is probably why Ephraim is viewed here as more numerous than Manasseh.
