Ulangan 24:1

24:1 If a man marries a woman and she does not please him because he has found something offensive ¹  in her, then he may draw up a divorce document, give it to her, and evict her from his house.

Yesaya 50:1

50:1 This is what the Lord says:

“Where is your mother’s divorce certificate

by which I divorced her?

Or to which of my creditors did I sell you? ² 

Look, you were sold because of your sins; ³ 

because of your rebellious acts I divorced your mother. ⁴ 

[24:1]  ¹ tn Heb “nakedness of a thing.” The Hebrew phrase עֶרְוַת דָּבָר (’ervat davar) refers here to some gross sexual impropriety (see note on “indecent” in Deut 23:14). Though the term usually has to do only with indecent exposure of the genitals, it can also include such behavior as adultery (cf. Lev 18:6-18; 20:11, 17, 20-21; Ezek 22:10; 23:29; Hos 2:10).

[50:1]  ² sn The Lord challenges the exiles (Zion’s children) to bring incriminating evidence against him. The rhetorical questions imply that Israel accused the Lord of divorcing his wife (Zion) and selling his children (the Israelites) into slavery to pay off a debt.

[50:1]  ³ sn The Lord admits that he did sell the Israelites, but it was because of their sins, not because of some debt he owed. If he had sold them to a creditor, they ought to be able to point him out, but the preceding rhetorical question implies they would not be able to do so.

[50:1]  ⁴ sn The Lord admits he did divorce Zion, but that too was the result of the nation’s sins. The force of the earlier rhetorical question comes into clearer focus now. The question does not imply that a certificate does not exist and that no divorce occurred. Rather, the question asks for the certificate to be produced so the accuser can see the reason for the divorce in black and white. The Lord did not put Zion away arbitrarily.
