2 Maccabees 1:18

Therefore whereas we are now purposed to keep the purification of the temple upon the five and twentieth day of [the month] Casleu, we thought it necessary to certify you thereof, that ye also might keep [it, as the feast] of the tabernacles, and of the fire, [which was given us] when Neemias offered sacrifice, after that he had builded the temple and the altar.
