The making of bricks was the chief labor of the Israelites in Egypt (Exodus 1:13-14).
Those found among the ruins of Babylon and Nineveh are about a foot square [30.48 centimeters] and four inches thick [10.16 centimeters].
They were usually dried in the sun, though also sometimes in kilns (2 Samuel 12:31; Jeremiah 43:9; Nahum 3:14). (See NEBUCHADNEZZAR.)
The bricks used in the tower of Babel were burnt bricks, cemented in the building by bitumen (Genesis 11:3).

Bricks were also used in the walls of the biblical city of Jericho. See: Is the Bible accurate concerning the destruction of the walls of Jericho?
