1 Kings 8:64-65

64The same day did the king hallow the middle of the court that was before the house of Yhwh: for there he offered burnt offerings, and grain offerings, and the fat of the peace offerings: because the brasen altar that was before Yhwh was too little to receive the burnt offerings, and grain offerings, and the fat of the peace offerings.

65And at that time Solomon held a feast, and all Israel with him, a great congregation, from the entering in of Hamath unto the river of Egypt, before Yhwh our God, seven days and seven days, even fourteen days.
