Numbers 22:8 - Matthew Poole's English Annotations on the Holy Bible

The night was the time when God used to reveal his mind by dreams. Here is the first discovery of his wickedness, that he hakes time to consider, and doth his endeavour to effect that wicked notion of cursing the Israelites, which he should have rejected and abhorred at the first mention of it. As the Lord shall speak, Heb. Jehovah, the true God, whom he here mentions, either for his own greater reputation, as if he consulted not with inferior spirits, as other soothsayers did, but with the supreme God; or rather because this was Israel's God, and the only possible way of ruining them was by engaging their God against them; as the known way of the Romans and other heathens, when they went to besiege any city, they used enchantments to call forth that god under whose peculiar protection they were. The princes of Moab, and of Midian too, as is manifest from Numbers 22:7, which was needless to repeat here.
