Merodach has given a son, (Isa. 39:1), "the hereditary chief of the Chaldeans, a small tribe at that time settled in the marshes at the mouth of the Euphrates, but in consequence of his conquest of Babylon afterwards, they became the dominant caste in Babylonia itself." One bearing this name sent ambassadors to Hezekiah (B.C. 721). He is also called Berodach-baladan (2 Ki. 20:12; 2 Chr. 20:31).
