Charles Ellicott Commentary 1 Kings 3:15

"And Solomon awoke; and, behold, it was a dream: and he came to Jerusalem, and stood before the ark of the covenant of Jehovah, and offered up burnt-offerings, and offered peace-offerings, and made a feast to all his servants." — 1 Kings 3:15 (ASV)

Stood before the ark of the covenant, in its Tabernacle on Mount Zion, which now constituted a second, and probably still more sacred, place of worship. The great sacrifice—now distinctly a thank-offering, followed as usual by a sacred feast—is naturally repeated there.
