What are the implications of the word "Nofeil"?
Rashi #1 (citing Targum Onkelos): It implies that Hashem appeared to Bil'am ("u'Gelui Einayim") at night-time when he was lying in bed.
Rashi (citing the Midrash Agadah) and Targum Yonasan on Pasuk 3): Whenever Hashem appeared to Bil'am, he was unable to remain standing 1 and he would fall on his face. 2
Sanhedrin, 105a: It teaches us via a Gezeirah Shavah "Nofeil" "Nofeil" from Haman - "ve'Haman Nofeil al ha'Mitah" (Esther, 7:8) that Bil'am performed sorcery via his penis. 3
Rashi: Because he was uncircumcised and it was disgusting for him to stand upright before Hashem when He revealed Himself to him. See also Ba'al ha'Turim.
Targum Yonasan (Ibid.): Because he was not circumcised he fell on his face until the angel (conveying the prophecy) had finished. (It is not clear however, why Targum Yonasan mentions this in the previous Pasuk and not here)?
See Torah Temimah, note 3.
