Balaam the son of Beor was from the first a worshipper in some sort of the true God; and had learned some elements of pure and true religion in his home in the far East, the cradle of the ancestors of Israel. But though prophesying, doubtless even before the ambassadors of Balak came to him, in the name of the true God, yet prophecy was still to him as before a mere business, not a religion. The summons of Balak proved to be a crisis in his career: and he failed under the trial. When the gold and honors of Balak seemed to be finally lost, he became reckless and desperate; and, as if in defiance, counseled the evil stratagem by which he hoped to compass indirectly that ruin of God’s people which he had been withheld from working otherwise. He thus, like Judas and Ahithophel, set in motion a train of events which involved his own destruction.
The name Balaam signifies “destroyer,” or “glutton,” and is in part identical with “Bela, son of Beor,” the first king of Edom Genesis 36:32. The name “Beor” (“to burn up”) is that of the father, or possibly ancestor, of the prophet.
