1 Kings 3:4

To Gibeon—for that was the great high place— Of all the high places where the people sacrificed, Gibeon was the great and celebrated one, because the tabernacle and brazen altar were there. See 2 Chronicles 1:3. There is no reason to suppose, that the thousand sacrifices which Solomon is said to have made here, were offered in one day. The king, we may imagine, upon one of the great festivals, went in procession with his nobles to pay his devotion in Gibeon. Each of the great festivals lasted for seven days: but Solomon might stay much longer at Gibeon, until, by the daily oblations, a thousand burnt-offerings were consumed; and at the conclusion of this course of devotion, he might offer up his ardent prayer to God for wisdom, as recorded in the next verses. See 2 Chronicles 1:7.
