John Gill Commentary 1 Kings 8:49

"then hear thou their prayer and their supplication in heaven thy dwelling-place, and maintain their cause;" — 1 Kings 8:49 (ASV)

Then hear you their prayers, and their supplication, in
heaven your dwellingplace
For their deliverance out of captivity: and maintain their cause; plead it, and do them justice, avenge their injuries, and deliver them.
