Keluaran 4:22

4:22 You must say ¹  to Pharaoh, ‘Thus says ²  the Lord, “Israel is my son, my firstborn, ³ 

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? ⁴ 

Look, you were sold because of your sins; ⁵ 

because of your rebellious acts I divorced your mother. ⁶ 

[4:22]  ¹ tn The sequence of the instruction from God uses the perfect tense with vav (ו), following the preceding imperfects.

[4:22]  ² tn The instantaneous use of the perfect tense fits well with the prophetic announcement of what Yahweh said or says. It shows that the words given to the prophet are still binding.

[4:22]  ³ sn The metaphor uses the word “son” in its connotation of a political dependent, as it was used in ancient documents to describe what was intended to be a loyal relationship with well-known privileges and responsibilities, like that between a good father and son. The word can mean a literal son, a descendant, a chosen king (and so, the Messiah), a disciple (in Proverbs), and here, a nation subject to God. If the people of Israel were God’s “son,” then they should serve him and not Pharaoh. Malachi reminds people that the Law said “a son honors his father,” and so God asked, “If I am a father, where is my honor?” (Mal 1:6).

[50:1]  ⁴ 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]  ⁵ 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]  ⁶ 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.
