There is still another way of explaining our verse. Bileam realised that only someone who is good himself is worthy to bless G'd's people, (compare Proverbs 22,9: "the generous man is blessed"); our sages in Sotah 38 suggest that in order to correctly understand this verse in Proverbs the word Yevorach "blessed," should be punctuated as if it had been written yevarech i.e. "he will bless." Inasmuch as Bileam was known for his avarice, he was obviously not suited to be the instrument G'd would choose to bless His people. Bileam now understood that he personally was unfit to bless the people and that the blessings which had come out of his mouth had been spoken by the angel. This is why he concluded that there was no point in heaping more sin upon himself by consulting his charms. Instead, he faced the desert, a place described in Exodus 18,5 as the place where G'd's Presence rests. Bileam made a spiritual turnabout, became a penitent, -but only in order to become worthy to bless the lsraelites.-The Torah informs us that he did not do so out of free volition, but לפנים, he did so in order to deceive G'd into believing he had done תשובה. Perhaps he did so only in order to fool the angel who had put the bar in his mouth. If he could get the angel to remove the bar, he would pronounce blessings of his own accord which were designed to cause harm to the people receiving same. According to Sanhedrin 105 he actually did so when he said כנחלים נטיו, "as valleys stretched out, etc." (24,6). The Talmud points out that this meant that the Israelites should not have orchards and vineyards. Fortunately, the Holy Spirit invalidated Bileam's evil intention, turning these so-called blessings into the real thing.

A Midrashic approach based on Tanchuma Vezot Haberachah 1: the letter ו at the beginning of the word וזאת means that Moses added something over and above the blessing which had been bestowed on the people by Bileam. Bileam should really have bestowed seven blessings on the people corresponding to each of the seven altars he had built at the time. However, if you will check you will find that Bileam only uttered three blessing instead of seven (We know this from Balak who remonstrated with him saying: “here you have blessed them three times (Numbers 24,10). In view of this, G’d said to him: “you wicked and niggardly person; seeing that you are too jealous to bestow the proper number of blessings on these people, I will appoint Moses, who is more generous than you to complete the blessings these people are entitled to. This is the meaning of Proverbs 22,9: “the generous one is blessed (יבורך); do not read the word as יבורך but as יברך, “he will bestow blessing.” The person whom Solomon refers to in this verse is none other than Moses. He was anxious to bless Israel, and he completed the four blessings Bileam had withheld from the people. The first one of those four is found in Exodus 39,43: “Moses saw the entire work, and behold!-they had done it all as Hashem had commanded, so had they done; and Moses blessed them.” The second occasion Moses blessed the people is in Leviticus 9,23: ”Moses and Aaron came to the Tent of Meeting; they came out and blessed the people and the attribute of כבוד appeared to the entire nation.” The third time Moses blessed the people was in Deut. 1,11: “May Hashem, the G’d of your fathers continue to increase you one thousand-fold and bless you as He has said to you.” The fourth occasion when Moses blessed the people begins in our portion with the words: “and this is the blessing, etc.”

There may also be another meaning, similar to what we are told in Shabbat 34 where Rabbi Shimon bar Yochai put his eye on a sinner and that sinner died as a result. At first glance, how are we to understand that a pious person of the calibre of Rabbi Shimon bar Yochai would summarily "execute" someone by giving him "the eye?" The same Rabbi Shimon bar Yochai had castigated people of the evil eye as possessing a very negative virtue (Zohar 3, page 211). Actually, the exact wording in the Talmud was יהבי עיניה, "he looked at him with his eye" (singular). We would have expected the Talmud to say that "he looked at him with his eyes (pl)." We have to remember that inasmuch as "evil" and "death" are synonymous how is it that evil exists at all? This is because there are no absolutes; just as the attribute of Mercy contains a small part of the attribute of Justice, so every good virtue contains a small element of evil, and vice versa. In the case of evil, death occurs when that small part of "good" or "life" which kept it alive is withdrawn. Keeping this in mind, we can understand the peculiar statement in Sukkah 52 according to which G'd will slaughter the evil urge at an appropriate time in the future in the presence of the righteous. How are to understand this? How can one slaughter an angel (disembodied spirit)? Considering what we have just said we can understand the statement in the Talmud very easily. G'd will remove the part of the evil urge which makes it a viable i.e. active force.
