Adonijah the son of Haggith - Who this woman was we know not; Adonijah was evidently David's eldest son now living, and one of whom his father was particularly fond; see 1 Kings 1:6.
Prepared him chariots and horsemen - He copied the conduct of his brother Absalom in every respect. See 2 Samuel 15:1.
