They made Solomon - king the second time - The first time of his being anointed and proclaimed king was when his brother Adonijah affected the throne; and Zadok, Nathan, and Benaiah anointed and proclaimed him in a hurry, and without pomp. See 1 Kings 1:39. Now that all is quiet, and David his father dead, (for he was probably so at the time of the second anointing), they anointed and proclaimed him afresh, with due ceremonies, sacrifices, etc.
To be the chief governor - To be the vicegerent or deputy of Jehovah; for God never gave up his right of king in Israel; those called kings were only his lieutenants: hence it is said, 1 Chronicles 29:23, "that Solomon sat on the throne of the Lord as king instead of David his father."
King the second time - Solomon‘s first appointment was at the time of Adonijah‘s rebellion (marginal reference). As that appointment was hurried and, comparatively speaking, private, David now thought it best formally to invest Solomon a second time with the sovereignty, in the face of all Israel. For a similar reason a second and public appointment of Zadok alone to the high priest‘s office took place. Abiathar was not as yet absolutely thrust out; but it may be doubtful whether he was ever allowed to perform high priestly functions after his rebellion 1 Kings 1:7; 1 Kings 2:27.
