Job 31:10

then let my wife turn the millstone ¹  for another man, and may other men have sexual relations with her. ² 

Ex 11:5; 2Sa 12:11; Isa 47:2; Jer 8:10; Ho 4:13,14; Mt 24:41

¹ tn Targum Job interpreted the verb טָחַן (takhan, “grind”) in a sexual sense, and this has influenced other versions and commentaries. But the literal sense fits well in this line. The idea is that she would be a slave for someone else. The second line of the verse then might build on this to explain what kind of a slave – a concubine (see A. B. Davidson, Job, 215).

² tn Heb “bow down over her,” an idiom for sexual relations.

sn The idea is that if Job were guilty of adultery it would be an offense against the other woman’s husband, and so by talionic justice another man’s adultery with Job’s wife would be an offense against him. He is not wishing something on his wife; rather, he is simply looking at what would be offenses in kind.
