[3] "Balaam (בלעם) son of Beor" appears in a well-known story in Numbers, where he is asked to curse the Israelites but repeatedly blesses them instead.
[4] Later, he is mentioned as the instigator of tempting the Israelites into sin at Mount Peor,[5] for which he is eventually killed.
[6] He is mentioned in passing in Deuteronomy, in a passage which repeats a synopsis of earlier biblical stories.
The Talmud says in Baba Bathra 15b, "Seven prophets prophesied to the heathen, namely, Balaam and his father, Job, Eliphaz the Temanite, Bildad the Shuhite, Zophar the Naamathite, and Elihu, the son of Barachel the Buzite."
In the King James translation of 2 Peter 2:15, Beor is called Bosor (from the Greek Βεὼρ).
