1 Kings 3:4

to Gibeon The Hivite city which was assigned by Joshua to the tribe of Benjamin (Joshua 18:21-25). It is most known in early times for the cunning device of its inhabitants to secure a treaty with Joshua and the Israelites (Joshua 9), and in later history because it was the place where the tabernacle of the congregation and the brazen altar of burnt-offering were set up until the completion of Solomon's temple. Whether this position was chosen as a high place by the Israelites or whether it had been a place used for worship by the Hivites beforetime there is nothing to indicate.

the great high place Probably because the tabernacle was there. This was likely to make it more famous than its neighbours at Ramah or Mizpeh.

a thousand burnt offerings In the Chronicles (2 Chronicles 1:2-3) we are told a little more about this sacrifice. The king had consulted all the people, and the great officers, and went up in a solemn procession with all the congregation. This accounts for the abundance of the offerings. After this occasion we hear no more of sacrifices at Gibeon.
