John Gill Commentary 1 Kings 8:42

"(for they shall hear of thy great name, and of thy mighty hand, and of thine outstretched arm); when he shall come and pray toward this house;" — 1 Kings 8:42 (ASV)

(For they shall hear of your great name Of his great name, Jehovah; of him as the eternal, immutable, and self-existent Being; of the perfections of his nature, as displayed in his mighty works:

and of your strong hand, and of your stretched out arm) which had done formerly such mighty works in Egypt, at the Red sea, in the wilderness, in the land of Canaan, in the times of David, and still under the reign of Solomon, and even in future ages, besides the works of creation and providence in general:

when he shall come and pray towards this house not being admitted into it, only into a court, which in later times was called the court of the Gentiles, see (Acts 21:19) .
