4623. siopao (see-o-pah'-o)

from siope (silence, i.e. a hush; properly, muteness, i.e. involuntary stillness, or inability to speak; and thus differing from sige, which is rather a voluntary refusal or indisposition to speak, although the terms are often used synonymously); to be dumb (but not deaf also, like kophos properly); figuratively, to be calm (as quiet water)

dumb, (hold) peace.
