Adonijah

my Lord is Jehovah. (1.) The fourth son of David (2 Sam. 3:4).
After the death of his elder brothers, Amnon and Absalom, he
became heir-apparent to the throne. But Solomon, a younger
brother, was preferred to him. Adonijah, however, when his
father was dying, caused himself to be proclaimed king. But
Nathan and Bathsheba induced David to give orders that Solomon
should at once be proclaimed and admitted to the throne.
Adonijah fled and took refuge at the altar, and received pardon
for his conduct from Solomon on the condition that he showed
himself "a worthy man" (1 Kings 1:5-53). He afterwards made a
second attempt to gain the throne, but was seized and put to
death (1 Kings 2:13-25).

(2.) A Levite sent with the princes to teach the book of the
law to the inhabitants of Judah (2 Chr. 17:8).

(3.) One of the "chiefs of the people" after the Captivity
(Neh. 10:16).
