Matthew Poole and continuators on 1 Chronicles 29:23

23 Then Solomon sat on the throne of the LORD as king in stead of David his father, and prospered, and all Israel obeyed him.

i. e. On the Throne of Israel▪ which is called the Throne of the Lord, either more generally as all Thrones are the Lords, by whom Kings reign, Prov. 8. 15. and Magistrates are ordained, Rom. 13. 1, 2. or more specially and peculiarly; Either 1. because the Lord himself was in a peculiar manner the King and Governour of Israel, not onely in the time of the Judges, but afterward, Psal. 44. 4. & 89. 18. & 149. 2. Isa▪ 33. 22. or 2. because it was the Throne of Christ the Lord, whose Vicegerents David and Solomon and their Successors were, for whom this Throne was reserved, and by whom it was to be established and enjoyed for ever, Luke 2. 32. 33. Or 3. The Throne of the Lord is put for, The Throne of the People of the Lord, by a concise and short manner of Speech which is frequent in the Hebrew Language, as when the Key of David is put for the Key of the House of David; and the Mountain of the Lord, for the Mountain of the Lords House: Or 4. Because this Throne fell to Solomon not by right of Inheritance▪ for he had Elder Brethren, but by the special Appointment and Gift of the Lord. And so this, of the Lord, is the genitive case of the Efficient, as the Learned call it, and signifies, which the Lord gave him.
