John Gill Commentary 1 Kings 10:9

"Blessed be Jehovah thy God, who delighted in thee, to set thee on the throne of Israel: because Jehovah loved Israel for ever, therefore made he thee king, to do justice and righteousness." — 1 Kings 10:9 (ASV)

to establish them as a kingdom for ever as they were, so long as obedient to him; see (2 Chronicles 9:8) ,

therefore made he thee king, to do judgment and justice ;
not merely for the sake of honour and glory, much less to indulge to pleasure and luxury, and still less to oppression and tyranny; but to administer justice and judgment to the people, which is the principal end of government; see (Psalms 72:1Psalms 72:2) .
