'Cubits' in the Bible

Then King Jehoash of Israel captured Judah's King Amaziah, the son of Jehoash and grandson of Ahaziah, at Beth-shemesh. He went to Jerusalem and demolished 400 cubits of the wall of Jerusalem from the Ephraim Gate to the Corner Gate.

The height of one of the pillars was eighteen cubits, and the capital on top of it was three cubits high. A latticework carved in the form of pomegranates encircled the capital, crafted completely out of brass. The second pillar was identical to the first.
