Haweis(i)
17 Now this I say, the covenant confirmed of God to Christ, the law, which was given three hundred and thirty years after, cannot disannul, so as to vacate the promise.
18 For if the inheritance is of the law, it is no more by promise; but to Abraham God gave it freely by promise.
19 To what end then was the law given? It was given on account of transgressions, until that seed should come to whom the promise was made, being delivered through the ministry of angels into the hand of a mediator.
