He garnished the house with precious stones for beauty A great many precious stones were dedicated to God 1Ch 29:2; 1 Chronicles 29:8, and these were set here and there where they would show to the best advantage. And the gold was gold of Parvaim That is, of Taprobana, or Ceylon, as Bochart hath satisfactorily proved. See note on 1 Kings 9:28. With this gold, which was deemed the best, Solomon overlaid even the beams, the posts, the walls, and the doors, graving also cherubim on the walls The finest houses now pretend to no better garnishing than good paint on the doors, posts, and walls: but the ornaments of the temple were more substantially rich. For it was to be a type of the New Jerusalem, which has therefore no temple in it, because it is all temple, and the walls, gates, and foundations of it are said to be precious stones and pearls.
