God is not a man, that he should lie; neither the son of man, that he should repent: hath he said, and shall he not do it? or hath he spoken, and shall he not make it good? (Numbers 23:19)
It seems strange that Balaam did not sense that he was treating Jehovah as if He were altogether a man, to be influenced to change His mind. Such was a purely heathen concept.
Neither the son of man.
The word here translated “man” is the generic word meaning any member of the human race; God is not a mere mortal.
Repent.
In the sense of grieving over one’s doings. The change of location, the additional altars and the sacrifices offered on them, did not convince Jehovah that He had made a mistake in not being influenced by the first location and offerings. It is only a sincere turning away from evil by the sinner that can influence God to withhold due punishment (see Jer. 18:8; 26:3; Mal. 3:6; Rom. 11:29; James 1:17).
