Thats what God asked to of the silly people who teach that He divorced Israel. He simply punished her by putting her away but as seen in verse two He will redeem her.
Isaiah 50:1 Thus saith the Lord, Where is the bill of your mother's divorcement, whom I have put away? or which of my creditors is it to whom I have sold you? Behold, for your iniquities have ye sold yourselves, and for your transgressions is your mother put away. 2 Wherefore, when I came, was there no man? when I called, was there none to answer? Is my hand shortened at all, that it cannot redeem?
The bill of divorcement is simply a warning that He never carried through as seen in Isaiah 50.
Jeremiah 3:14 Turn, O backsliding children, saith the Lord; for I am married unto you: and I will take you one of a city, and two of a family, and I will bring you to Zion:
God said He would never forsake His people.
In Deuteronomy 4:31, God made a promise never to forsake His people, "For the LORD thy God is a merciful God; he will not forsake thee, neither destroy thee, nor forget the covenant of thy fathers which he sware unto them."
Those who teach that God divorced the Jewish people need to rethink their position on certain verses or agree that they believe God did not stand jup to His promises.
Then Judah/Zion is the married wife, having never been divorced - So who is the barren woman (Is 54) told to jump for joy after the death of Messiah (Is 53)? Here is another hint: How was she widowed?
