Gibeon - The transfer to Gibeon of the “tabernacle of the congregation,” and the brass “altar of burnt offerings” made by Moses, which were removed there from Nob (compare 1 Samuel 21:6, with marginal references “i,” “k”), had made it “the great high-place,” more sacred, i. e., than any other in the holy land, unless it were Mount Zion where the ark had been conveyed by David. For the position of Gibeon, see Joshua 9:3 note.
A thousand burnt offerings did Solomon offer - Solomon presented the victims. The priests were the actual sacrificers 1 Kings 8:5. A sacrifice of a thousand victims was an act of royal magnificence suited to the greatness of Solomon. So Xerxes offered 1,000 oxen at Troy. If the offerings in this case were “whole burnt offerings,” and were all offered upon the altar of Moses, the sacrifice must have lasted several days.
