JMNT(i)
14 At about that time, one of the twelve – the person normally called Judah (or: Judas) of Iscariot – was going on his way to the chief (or: ranking) priests.
15 He said, "What are you presently willing to give to me? – and I, myself, will proceed in turning Him over to you men!" “So they stacked up for him thirty silver coins [= the going price for a slave; some MSS read instead: thirty staters (an Attic silver coin, equal in value to the Jewish shekel, or four denarii's)].” [Zech. 11:12]
16 And so, from that point on, he kept on seeking a good opportunity for the purpose of turning Him in (or: a suitable situation so that he could hand Him over).
