“Give the king Thy judgments, O God, and Thy righteousness unto the king’s son. He shall judge Thy people with righteousness, and Thy poor with judgment.” Psalm 72:1-2 (KJV)
This is a Psalm most likely written by David to his son Solomon. The title of it says, “A Psalm for Solomon.” Solomon was part of the Davidic dynasty which God ordained.
Of this verse the MacArthur Study Bible note reads,
Your judgments. A prayer that the king would faithfully mediate God’s justice on the nation (cf. Deut. 17:18-20). the king’s Son. A reference primarily to Solomon, emphasizing his bond with the Davidic dynasty; but it also anticipates Messiah’s reign as the culmination of the Davidic covenant (cf. 2 Sam. 7:12, 13; Ps. 2:1-12).
This was a prayer for Solomon to be a just and right judge for the people of all the people of Israel. He was to represent the right and just rule of the coming King who would be the Right and Just Judge of all the earth.
The Just and Righteous King is Jesus Christ. He is coming soon. Though we do not know the day or the hour. We are told to be ready. Believe His Word, trust Him, live for Him.
