Mark 14:11

ἐχάρησαν, they rejoiced; when one of the twelve companions of Jesus unexpectedly turned up ready to deliver his Master into their hands. A most vivid feature omitted by Mt. in his summarising way. Well might they rejoice, as but for this windfall they might have been totally at a loss how to compass their end. ἐπηγγείλαντο, they promised to pay, did not actually pay on the spot, as Mt.'s statement implies (ἔστησαν, Mark 14:15). ἐζήτει, cf. ἐζήτουν, Mark 14:1, in reference to the Sanhedrists. They were seeking means of getting rid of Jesus; Judas was now on the outlook for a chance of betraying Him into their hands. εὐκαίρως here and in 2 Timothy 4:1, the adjective and verb in Mark 6:21; Mark 6:31, the noun in Matthew 26:16.
