'Common' in the Bible

Elisha asked the king of Israel, "What do I have in common with you? Go visit your parents' prophets." The king of Israel replied, "No! The LORD has summoned these three kings so he can hand them over to Moab!"

He brought the Asherah from the LORD's Temple to the Kidron Brook outside Jerusalem, burned it at the Kidron brook, pulverized the ashes to dust, and scattered it over the graves of the common people.
