Chaereas

ke'-re-as (Chaireas; the King James Version Chereas): Brother of Timotheus, the Ammonite leader against Judas Maccabeus (1 Macc 5:6). He held the fortress of Gazara (the "Jazer" of 1 Macc 5:8) to which Timotheus fled from Judas. The latter pursued him and captured the fortress after a vigorous siege. In the slaughter which followed the two brothers, Chaereas and Timotheus, were killed (2 Macc 10:32,37).
