For from the top of the rocks ... - The “for” indicates the constraint under which Balaam felt himself. He had been met by God in his own way; from the cliff he had watched for the expected augury; and by the light of this he here interprets, according to the rules of his art, the destiny of Israel.
Dwell alone - i. e., apart from others, undisturbed by their tumults, and therefore in safety and just security. Compare the same idea in marginal reference; Jeremiah 49:31; and Micah 7:14. This tranquility was realized by the Israelites so long as they clave to God as their shelter and protection. But the inward “dwelling alone” was the indispensable condition of the outward “dwelling alone,” and so soon as the influence of the pagan world affected Israel internally, the external power of paganism prevailed also. Balaam himself, when he eventually counseled tempting the people into sin, acted upon the knowledge that God’s blessing and Israel’s prosperity depended essentially on faithfulness to God.
