to cut off: to sever a piece cleanly away with a blade, whether a stick from a tree or the wool from a sheep
This verb appears only twice in the whole Hebrew Bible, and both times it names the same plain action: a blade taking a piece off something. In 2 Kings the prophet Elisha helps a workman who has lost a borrowed iron axe head in the Jordan; Elisha cuts a stick free, throws it in, and the iron comes back up. In the Song of Songs a bride's teeth are praised by comparing them to a flock of ewes fresh from the washing with their wool cut off, gleaming white and matched top to bottom with none missing.
Two verses is very little to work from, so the word's shape is largely read off its relatives. A noun built on the same root (קֶצֶב) names not the cutting but its result: the form something has been cut to, which is how the temple account can say the two winged figures in the inner room were made to one measure and one form. Later Hebrew and Aramaic pushed the root in two further directions, toward the butcher who cuts up meat and toward a fixed allowance, an amount cut to a set size. Both of those later uses keep the original idea of a cut that fixes a limit.
The two biblical uses stay close together. Cutting a stick from a tree and clipping the fleece off a sheep are the same motion applied to different stuff, and both leave a clean edge where something has been taken away. That is why English Bibles need two words, "cut" in Kings and "shorn" in the Song, to carry one Hebrew verb.
