We continue our study by reviewing a bit of 3:15-18 and taking a closer look at verse 19 to discover why the law was given and possibly why the angels were involved.
Verse 19: Wherefore then serveth the law? It was added because of transgressions, till the seed should come to whom the promise was made; and it was ordained by angels in the hand of a mediator. His question was if the covenant had nothing to do with the law, why was the law later given? His answer was that it was added because of transgressions, till the seed should come to whom the promise was made; and it was ordained by angels in the hand of a mediator.
The context clearly dictates that the transgressions he is referring to are those of the nation of Israel and the Law would serve as a preservation agent for the nation until the seed (Christ) should come to whom the promise was made.
How was it ordained by angels? This may be a reference to Deuteronomy 33:1-2 which says, And this is the blessing, wherewith Moses the man of God blessed the children of Israel before his death. And he said, The LORD came from Sinai, and rose up from Seir unto them; he shined forth from mount Paran, and he came with ten thousands of saints: from his right hand went a fiery law for them. First, the word saints in this verse are referring to holy ones or angels. Second, if this verse is what Paul is referring to, that would make Moses the mediator between God and the nation just as described in Exodus 20:19-22 where it says, And they said unto Moses, Speak thou with us, and we will hear: but let not God speak with us, lest we die. And Moses said unto the people, Fear not: for God is come to prove you, and that his fear may be before your faces, that ye sin not. And the people stood afar off, and Moses drew near unto the thick darkness where God was. And the LORD said unto Moses, Thus thou shalt say unto the children of Israel, Ye have seen that I have talked with you from heaven.
