'Cubits' in the Bible

And Jehoash, king of Israel, made Amaziah, king of Judah, the son of Jehoash, son of Ahaziah, prisoner at Beth-shemesh, and came to Jerusalem, and had the wall of Jerusalem pulled down from the doorway of Ephraim to the door in the angle, four hundred cubits.

One of the pillars was eighteen cubits high, with a crown of brass on it; the crown was three cubits high, circled with a network and apples all of brass; and the second pillar had the same.
