C. F. Keil and Franz Delitzsch on Numbers 24:10-11

Num 24:10-11

This repeated blessing of Israel threw Balak into such a violent rage, that he smote his hands together, and advised Balaam to fly to his house: adding, “I said, I will honour thee greatly (cf. Num 22:17 and Num 22:37); but, behold, Jehovah has kept thee back from honour.” “Smiting the hands together” was either a sign of horror (Lam 2:15) or of violent rage; it is in the latter sense that it occurs both here and in Job 27:23. In the words, “Jehovah hath kept thee back from honour,” the irony with which Balak scoffs at Balaam’s confidence in Jehovah is unmistakeable.
