Nombres 24:15

And he took up the parable of his prophecy, and said Bileam the son of Beor speaketh; the man speaketh who is more honourable than his father, because the mysteries hidden from prophets have been revealed to him;

He referred to himself now as one who heareth the words of G-d, and as one who seeth the vision of the Almighty, as he had done in the third prophecy, but he added now [the phrase] and knoweth the knowledge of the Most High. Now one who speaks in this manner, saying “I know the knowledge of a certain person” means to say that he understands him, and what is in his heart, [even] those matters which he does not utter verbally, and similarly this [man Balaam] intended to say that he knows and will now say what is in the “mind” [i.e., intention] of G-d the Most High to do in His world at the end of all days. This is similar to that which it says, for the day of vengeance is in My heart, and the Rabbis have said [with reference to that day, that its precise timing is a matter which “His] heart has not divulged to the mouth.” Now Scripture states here, And ‘he took up his parable,’ and said and it does not mention that this was [said] by prophecy, as it says about the [previous] three occasions, for since he said, The saying of him who heareth the words of G-d … who seeth the vision of the A lmighty it is self-understood that the hand of G-d was upon. him, just as at the third time, where it says: and the spirit of G-d came upon him; and he himself said so. (Verse 4) and it says there, and the spirit of G-d came upon him (Verse 2). So here too, in his fourth prophecy, where it says who heareth the words of G-d, who seeth the vision of the Almighty, it was also through the spirit of G-d which came upon him, even though it does not say so expressly.
