II Maccabees 2:16

16 Whereas we then are about to celebrate the purification, we have written unto you, and ye shall do well, if ye keep the same days.

II Maccabees 2:16 In-Context

14 In like manner also Judas gathered together all those things that were lost by reason of the war we had, and they remain with us,
15 Wherefore if ye have need thereof, send some to fetch them unto you.
16 Whereas we then are about to celebrate the purification, we have written unto you, and ye shall do well, if ye keep the same days.
17 We hope also, that the God, that delivered all his people, and gave them all an heritage, and the kingdom, and the priesthood, and the sanctuary,
18 As he promised in the law, will shortly have mercy upon us, and gather us together out of every land under heaven into the holy place: for he hath delivered us out of great troubles, and hath purified the place.
