Charles Ellicott Commentary 1 Chronicles 29:23

"Then Solomon sat on the throne of Jehovah as king instead of David his father, and prospered; and all Israel obeyed him." — 1 Chronicles 29:23 (ASV)

Then. —And.

Solomon sat on the throne of the Lord. —Compare to 1 Chronicles 28:5.

As king instead of David his father. —It is not meant that David abdicated. 1 Chronicles 29:23–25 are anticipative of the history of Solomon’s reign. At the same time, their introduction here is natural, not only as relating the immediate sequel of Solomon’s coronation, but also as showing how David’s last wishes in regard to his son were realised.
