1 Kings 1:5 - Ellicott's Commentary On The Whole Bible

Adonijah (my Lord is Jehovah), David’s fourth son, born in Hebron (2 Samuel 3:4), at least thirty-three years before. From the words of Solomon in 1 Kings 2:22, we may gather that he claimed the throne as being now the eldest son. Hence it is probable that Chileab (or Daniel, see 2 Samuel 3:3; 1 Chronicles 3:1), the second son, was dead, as well as Amnon and Absalom. The similarity between Adonijah and Absalom, in respect of personal beauty, favour with a too-indulgent father, ambition and trust in popularity, is evidently suggested by the narrative, which places them in close connection, although born of different mothers. The means, moreover, which Adonijah employed, the body-guard of fifty men, and the maintenance of “chariots and horsemen,” are exactly imitated from the example of Absalom (2 Samuel 15:1); and we note that the festal sacrifice, with the support of two important leaders in peace and war, recalls the same model. But Adonijah hardly shows the craft and ruthless determination of the elder rebel. His attempt on the crown seems crude and ill-planned in conception, and wanting in promptitude of action.
