I Maccabees 16:13

13 Wherefore 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.

I Maccabees 16:13 In-Context

11 Moreover in the plain of Jericho was Ptolemeus the son of Abubus made captain, and he had abundance of silver and gold:
12 For he was the high priest's son in law.
13 Wherefore 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.
14 Now 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 Sabat:
15 Where the son of Abubus receiving them deceitfully into a little hold, called Docus, which he had built, made them a great banquet: howbeit he had hid men there.
