1 Maccabees 16:15 (Septuagint)

¹³Wherefore his heart being lifted up, he thought to get the country to himself, and thereupon consulted deceitfully against Simon and his sons to destroy them.

¹⁴Now Simon was visiting the cities that were in the country, and taking care for the good ordering of them; at which time he came down himself to Jericho with his sons, Mattathias and Judas, in the hundred threescore and seventeenth year, in the eleventh month, called Shebat:

— 1 Maccabees 16:15 —

¹⁶So when Simon and his sons had drunk largely, Ptolemy and his men rose up, and took their weapons, and came upon Simon into the banqueting place, and slew him, and his two sons, and certain of his servants.

¹⁷In which doing he committed a great treachery, and recompensed evil for good.
