Ulangan 27:20

27:20 ‘Cursed is the one who has sexual relations with ⁴  his father’s former wife, ⁵  for he dishonors his father.’ ⁶  Then all the people will say, ‘Amen!’

[18:8]  ¹ tn Heb “the nakedness of your father she is.” See the note on v. 7 above. This law refers to another wife of the man’s father, who is not that man’s mother. The laws in the Pentateuch sometimes assume the possibility that a man may have more than one wife (cf., e.g., Deut 21:15-17).

[20:11]  ² sn See the note on Lev 18:7 above.

[20:11]  ³ tn See the note on v. 9 above.

[27:20]  ⁴ tn Heb “who lies with” (so NASB, NRSV); also in vv. 22, 23. This is a Hebrew idiom for having sexual relations (cf. NIV “who sleeps with”; NLT “who has sexual intercourse with”).

[27:20]  ⁵ tn See note at Deut 22:30.

[27:20]  ⁶ tn Heb “he uncovers his father’s skirt” (NASB similar). See note at Deut 22:30.
