\Sheth\, n. The part of a plow which projects downward beneath the beam, for holding the share and other working parts; -- also called {standard}, or {post}.
tumult. (1.) "The children of Sheth" (Num. 24:17); R.V., "the sons of tumult," which is probably the correct rendering, as there is no evidence that this is a proper name here.
(2.) The antediluvian patriarch (1 Chr. 1:1).
