Ezekiel 23:2-4

2“Son of man, there were two women (Israel and Judah), the daughters of one mother (the united kingdom);

3and they prostituted themselves in Egypt. From their youth they were grossly immoral; in that place their breasts were embraced and their virgin bosom was grasped.

4Their names were Oholah the elder and Oholibah her sister, and they became Mine and they gave birth to sons and daughters. And as for [the identity of] their names, Oholah is Samaria (capital city of Israel) and Oholibah is Jerusalem (capital city of Judah).
