Merodach-baladan

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 Kings
20:12; 2 Chr. 20:31). (See HEZEKIAH T0001771.)
