And God said unto Balaam, thou shalt not go with them,.... Which is a denial of the first thing Balak requested, "come now, therefore", c. Numbers 22:6
thou shall not curse the people which was the principal thing desired, and in order to which he was solicited to go with the messengers; but this is absolutely forbidden:
for they are blessed; by the Lord himself, with an irrevocable blessing, and therefore it would be vain and fruitless, as well as dangerous for him to attempt to curse them, Genesis 12:3 this may have a special respect to the blessing of Jacob by Isaac, which could not be reversed by the solicitations of Esau, and which descended to Jacob's posterity, the Israelites, Genesis 27:33.
