John Gill 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)

And Solomon awoke, and, behold, [it was] a dream
Not that it was nothing but a dream, a natural one, a vain and empty one, but a divine and supernatural one, a dream of prophecy, as the Jews call it, or a prophetic dream; a true one, which had its fall accomplishment in him, the truth of which he perceived as soon as he awoke; for he found himself possessed of such a measure of wisdom and knowledge he never had before, which occasioned the thanksgiving and joy next expressed:

and he came to Jerusalem ;
from Gibeon, accompanied by his nobles and servants:

and stood before the ark of the covenant the Lord ;
which was in a tent David had pitched for it there, (2 Samuel 6:17); here he stood with holy reverence, as in the presence of the Lord, and as a servant of his, to minister to him, and as a worshipper of him, with a heart full of gratitude for the great things he had done for him, and promised to him:

and offered up burnt offerings, and offered peace offerings ;
by way of thankfulness for his quiet settlement in the for the Lord's appearance to him at Gibeon, and what he had already given, and promised to give:

and made a feast to all his servants ;
in a way of joy and gladness for the above layouts; this feast was either the part of the peace offerings he offered, which belonged to the offerer to eat with his friends, or this was a special feast made at his own palace for his courtiers.
