Why then was the law given? It (prosetethē | προσετέθη | aor pass ind 3 sg) was (prosetethē | προσετέθη | aor pass ind 3 sg) added (prosetethē | προσετέθη | aor pass ind 3 sg) because of transgressions, until the descendant should come to whom the promise had been made. It was established through angels by a mediator.
