And the angel of the Lord said unto Manoah,.... Giving him no direct answer to his question, either what should be done to the child, or what that should do; only reminds of and repeats what he had said to his wife, which she should be careful to observe and would, and that was enough for him to know:

of all that I said to the woman, let her beware; take to abstain from everything in eating and drinking during the time of her going with child, he had joined, which are particularly repeated in the next verse.

The angel of the Lord then repeated the instructions which he had already given to the woman in Judges 13:4, simply adding to the prohibition of wine and strong drink the caution not to eat of anything that came from the vine, in accordance with Numbers 6:3.

And the angel of the LORD said unto Manoah, Of all that I said unto the woman let her beware.

13:13 Let her - Whilst the child is in her womb, and after the child is born let him observe the same orders.

13:8-14 Blessed are those who have not seen, and yet, as Manoah, have believed. Good men are more careful and desirous to know the duty to be done by them, than to know the events concerning them: duty is ours, events are God's. God will guide those by his counsel, who desire to know their duty, and apply to him to teach them. Pious parents, especially, will beg Divine assistance. The angel repeats the directions he had before given. There is need of much care for the right ordering both of ourselves and our children, that we may be duly separate from the world, and living sacrifices to the Lord.
