Galatians 1:8; Galatians 3:19; Galatians 4:14

Galatians 1:8

8 But even if we, or an angel from heaven, should preach to you a gospel contrary to what we have preached to you, he is to be accursed!

Galatians 3:19

19 Why the Law then? It was added because of transgressions, having been ordained through angels by the agency of a mediator, until the seed would come to whom the promise had been made.

Galatians 4:14

14 and that which was a trial to you in my bodily condition you did not despise or loathe, but you received me as an angel of God, as Christ Jesus Himself.
