Cut, to cut off, manacle] (Numeric value: 7) Zayin is a paradoxical word, since it means "weapon" or "sword," but derives from a root word that means "sustenance" or "nourishment." The root (zan) appears in words like (mazon), meaning "food." Also, in chazown ChetZayinVavNun from 02372 to see, behold ChetZayinHey; n m; meaning vision. As we see in Nahum 1.
