'Identity' in the Bible

Their 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).

I will take the blood from their mouthsAnd their detestable things from between their teeth [those repulsive, idolatrous sacrifices eaten with the blood].Then they too will be a remnant for our God,And be like a clan in Judah,And Ekron will be like one of the Jebusites.

but he will [deny his identity and] say, ‘I am no prophet. I work the ground, because a man sold me as a slave in my youth.’
