JMNT(i)
2 And still, the chief (head; ranking) priests and the scribes (scholars; theologians) kept on trying to find how they could take Him up (= assassinate Him) – you see they were still fearing the people.
3 Now an adversary (or: an opposing purpose or attitude) entered into Judah (or: Judas) – the man normally being called Iscariot, being [a member] of the number of the twelve.
4 And so, after going off (or: away), he discussed (or: conferred) with the chief (or: head) priest and military leaders (or: officers) about how he could turn Him over to them.
5 Then they rejoiced and placed themselves together in agreement to give him silver coins.
