and said
In the prophecies of Balaam God testifies on behalf of His people rather than (as usual) to them. It is the divine testimony to their standing as a redeemed people in view of the serpent "lifted up," and of the water from the smitten rock. (Num 21:5-9); (Num 20:11). Their state was morally bad, but this was a matter concerning the discipline of God, not His judgment. The interpretation of the prophecies is literal as to Israel, typical as to Christians. Through Christ "lifted up" (Joh 3:14) our standing is eternally secure and perfect, though our state may require the Father's discipline; (Co1 11:30-32); (Co2 1:4-9); (Co2 1:10-13) meantime, against all enemies, God is "for us." (Rom 8:31).
