Ezekiel 23:43

Then said I unto her that was old in adulteries, Will they now commit whoredoms with her, and she with them?

Cross-reference

Jeremiah 13:23 asks if habitual evildoers can change — exactly the idea of being 'old in adulteries' and unable to stop.

Jeremiah 32:30 says Israel has done evil from their youth — parallels the 'old in adulteries' description of persistent sin.

Hosea 2:2 uses the same metaphor of an adulterous wife for Israel's unfaithfulness — direct parallel to the harlotry imagery.
