Ibn Ezra on Genesis 4:12/אבן עזרא על בראשית ד׳:י״ב

1[AND A WANDERER.] Some explain nad (wanderer) to mean a mourner, as in to bemoan (la-nud) him (Job 2:11). However, my opinion is that nad is a synonym for na (fugitive). Nedod (wander) in Lo, then would I wander (nedod) far off (Ps. 55:8) is analogous.
