Johanan (or John Gaddi/Caddis in the King James Version, Hebrew: יוחנן הגדי) was the oldest of the sons of Mattathias, and brother of Judas Maccabeus. He was one of the leaders of the revolt of the Maccabees in the 2nd century BC.
Death
The final references to John Gaddi are the events surrounding his death. This is the account found in 1 Maccabees: "And Jonathan sent his brother as leader of the multitude and begged the Nabateans, who were his friends, for permission to store with them the great amount of baggage which they had. But the sons of Jambri from Medeba came out and seized John and all that he had, and departed with it. After these things it was reported to Jonathan and Simon his brother, 'The sons of Jambri are celebrating a great wedding, and are conducting the bride, a daughter of one of the great nobles of Canaan, from Nadabath with a large escort.' And they remembered the blood of John their brother, and went up and hid under cover of the mountain."' (1 Maccabees 9:35-38 RSV-CE)
