1 Kings 8:64-66

64 The same day the king consecrated the middle of the court that was before the house of the  Lord, for there he offered the burnt offering and the grain offering and the fat pieces of the peace offerings, because a the bronze altar that was before the  Lord was too small to receive the burnt offering and the grain offering and the fat pieces of the peace offerings.

65 So Solomon held b the feast at that time, and all Israel with him, a great assembly, from c Lebo-hamath to d the Brook of Egypt, before the  Lord our God, seven days.
Septuagint; Hebrew  seven days and seven days, fourteen days
66 On the eighth day he sent the people away, and they blessed the king and went to their homes joyful and glad of heart for all the goodness that the  Lord had shown to David his servant and to Israel his people.
