Galatians 2:2

2:2 I went there because of a revelation and presented to them the gospel that I preach among the Gentiles. But I did so only in a private meeting with the influential people, to make sure that I was not running – or had not run – in vain.

Galatians 3:19

3:19 Why then was the law given? It was added because of transgressions, until the arrival of the descendant to whom the promise had been made. It was administered through angels by an intermediary.
