Matthew 26:14-16

Then one of the twelve [disciples], who was called Judas Iscariot, went to the chief priests and said, “What are you willing to give me if I hand Jesus over to you?” And they weighed out thirty pieces of silver. [Ex 21:32; Zech 11:12] And from that moment Judas began looking for an opportune time to betray Jesus. [Mark 14:10, 11; Luke 22:3-6; John 6:71]
