'Expedient' in the Bible

Nor do you understand that it is expedient and politically advantageous for you that one man die for the people, and that the whole nation not perish.”

But I tell you the truth, it is to your advantage that I go away; for if I do not go away, the Helper (Comforter, Advocate, Intercessor—Counselor, Strengthener, Standby) will not come to you; but if I go, I will send Him (the Holy Spirit) to you [to be in close fellowship with you].

It was Caiaphas who had advised the Jews that it was expedient for one man to die on behalf of the people.
