Numbers 23:3 - Matthew Poole's English Annotations on the Holy Bible

By thy burnt-offering; as in God's presence, as one that offers thyself its well as thy sacrifices to obtain his favour. I will go to some solitary and convenient place, where I may by my enchantments prevail with God to appear to me, and to answer thy and my desires in cursing this people. Whatsoever he showeth me, i.e. reveals to me, either by word or sign. To an high place; or, into the plain, as that word properly signifies, for he was now in a high place, Numbers 22:4. But this is not material, it was doubtless some solitary place, where he might use some gestures and ceremonies which he would not have others see, and where he might more reasonably expect to meet with God; for both good and evil spirits most commonly appeared to persons in such places.
