קבלה על במדבר 22:7

Rabbi Yosi said, Enchantment and divination are two kinds with the same level of strength. When Bilaam came to hurt Yisrael, he used divination, as it is written, "with divinations in their hand" (Num. 22:7). Laban used enchantment against Jacob, but neither succeeded. This is the meaning of the verse, "Surely there is no enchantment in Jacob, nor divination in Yisrael." The words, "there is no enchantment in Jacob," refer to the days of Laban, and "divination in Yisrael" refers to the latter days of Bilaam.
