'Backsliding Israel' in the Bible

The LORD said also unto me in the days of Josiah the king, Have you seen that which backsliding Israel has done? she has gone up upon every high mountain and under every green tree, and there has played the harlot.

And I saw, when for all the causes for which backsliding Israel committed adultery I had put her away, and given her a bill of divorce; yet her treacherous sister Judah feared not, but went and played the harlot also.

And the LORD said unto me, The backsliding Israel has justified herself more than treacherous Judah.

Go and proclaim these words toward the north, and say, Return, you backsliding Israel, says the LORD; and I will not cause my anger to fall upon you: for I am merciful, says the LORD, and I will not keep anger forever.
