Matthew 26:14-16, 47-50
Then one of the twelve, named Judas Iscariot, went to the chief priests,
and said, "What are you willing to give me to deliver Him up to you?" And they weighed out to him thirty pieces of silver. And from then on he began looking for a good opportunity to betray Him.

And while He was still speaking, behold, Judas, one of the twelve, came up, accompanied by a great multitude with swords and clubs, from the chief priests and elders of the people. Now he who was betraying Him gave them a sign, saying, "Whomever I shall kiss, He is the one; seize Him." And immediately he went toYeshua and said, "Hail, Rabbi!" and kissed Him. And Yeshua said to him, "Friend, do what you have come for." Then they came and laid hands on Yeshua and seized Him. Matthew 26:14-16,47-50
