Balaam is mentioned no less than fifty-one times in Kitvei HaKodesh, beginning with the account given in Parashat Balak (Numbers 22-24). He was later killed in a battle between Israel and the Midianites (Numbers 31:8). He is also mentioned in Deut 23:5-6; Joshua 13:22; 24:9-10; Micah 6:5; and Nehemiah 13:2.
Although at first glance Bil'am might appear to be a man of God, a true prophet, both the Scriptures and Jewish tradition are emphatic that he was an adversary of the LORD and an ememy of the children of Israel. His so-called sorcery led to folly and death. The New Testament Scriptures speak of "the way of Balaam, the son of Beor, who loved gain from wrongdoing" (2 Pet 2:15), "Balaam's error" (Jude 1:11), and "the teaching of Balaam, who taught Balak to put a stumbling block before the sons of Israel" (Rev 2:14).
Perhaps paradoxically, or at least ironically, the blessing that Bil'am was constrained to confess over Israel was integrated into the daily Shacharit service as the Mah Tovu.
