From the hills I behold him The hills on which he then stood. This and the former expression may relate not only to the present view he had of the camp of Israel, but to their future settlement in Canaan; wherein they were represented to the eye of his mind, as dwelling securely under the protection of the Almighty.
The people shall dwell alone Separated from other nations by peculiar laws, religion, and manners. See on Exodus 19:5; Leviticus 20:24-26; Exodus 3:8. By which means they had so little communication with the Gentiles, that they were called an unsociable people, and thought to have an enmity to the rest of the world, as we may read in Diodorus Siculus, Tacitus, and others.
And here we may reflect with the greatest admiration upon what Balaam said on this occasion; and be convinced that he was indeed under the influence of that Spirit to whom all things are known, at all times, from the beginning to the end. For how could he otherwise, as Bishop Newton properly argues, “upon a distant view only of a people whom he had never seen or known before, have discovered the genius and manners, not only of the people then living, but of their posterity to the latest generations? What renders it more extraordinary is, the singularity of the character, that they should differ from all the people in the world, and should dwell by themselves among the nations, without mixing and incorporating with any. The time too when this was affirmed increases the wonder, it being before the people were well known in the world, before their religion and government were established, and even before they had obtained a settlement anywhere; but yet that the character was fully verified in the event, not only all history testifies, but we have even ocular demonstration at this day. The Jews, in their religion and laws, their rites and ceremonies, their manners and customs, were so totally different from all other nations, that they had little intercourse or communication with them. An eminent author hath shown that there was a general intercommunity among the gods of paganism; but no such thing was allowed between the God of Israel and the gods of the nations. There was to be no fellowship between God and Belial, though there might be between Belial and Dagon. And hence the Jews were branded for their inhumanity and unsociableness; and they as generally hated, as they were hated by, the rest of mankind. Other nations, the conquerors and the conquered, have often associated and united, as one body, under the same laws; but the Jews, in their captivities, have commonly been more bigoted to their own religion, and more tenacious of their own rites and ceremonies, than at other times. And even now, while they are dispersed among all nations, they yet live distinct and separate from all, trading only with others, but eating, marrying, and conversing chiefly among themselves. We see, therefore, how exactly and wonderfully Balaam characterized the whole race, from the first to the last, when he said, Lo, the people shall dwell alone, and shall not be reckoned among the nations.”
