Deuteronomy 22:30 New English Translation

³⁰(23:1)^[a] A man may not marry^[b] his father’s former^[c] wife and in this way dishonor his father.^[d]

Deuteronomy 22:30 sn Beginning with 22:30, the verse numbers through 23:25 in the English Bible differ from the verse numbers in the Hebrew text (BHS), with 22:30 ET = 23:1 HT, 23:1 ET = 23:2 HT, 23:2 ET = 23:3 HT, etc., through 23:25 ET = 23:26 HT. With 24:1 the verse numbers in the ET and HT are again the same.
Deuteronomy 22:30 tn Heb “take.” In context this refers to marriage, as in the older English expression “take a wife.”
Deuteronomy 22:30 sn This presupposes either the death of the father or their divorce since it would be impossible for one to marry his stepmother while his father was still married to her.
Deuteronomy 22:30 tn Heb “uncover his father’s skirt” (so ASV, NASB). This appears to be a circumlocution for describing the dishonor that would come to a father by having his own son share his wife’s sexuality (cf. NAB, NIV “dishonor his father’s bed”).
