John Gill Commentary 1 Kings 8:32

"then hear thou in heaven, and do, and judge thy servants, condemning the wicked, to bring his way upon his own head, and justifying the righteous, to give him according to his righteousness." — 1 Kings 8:32 (ASV)

Then hear you in heaven
When the injured person makes supplication to have justice done him:

and do, and judge your servants ;
contending with one another, the one affirming, the other denying

condemning the wicked, by bringing his way upon his head :
inflicting upon him the punishment imprecated by him in his oath:

and justifying the righteous, to give him according to his
righteousness ;
by making it appear that his cause is just.
