Comentario sobre Números 21:30

ונירם means their sovreignty.

ונירם אבד, and what will be his domain he will lose seeing that after said מושלים, visionaries had predicted his rise to great power they had continued by revealing that they also foresaw his defeat at the hands of the Israelites.

ונירם, they were driven from their places. The word is similar to נחרם, they were banished. The construction is parallel to נטה and ונט. The word is derived from the root ירה, hence וניר, “vanir.” The vocalisation of vanirom means the same as if the Torah had written vanireym. We find a similar construction in Isaiah 56,3 yavdilani, which is the same as yavdileyni. Also in Exodus 14,11 lehotziani is the same as lehotzieyni. If we were to follow Onkelos’ translation, the vocalisation should have been veniram instead of vaniram.
