verb
33.117 · Communication · Keep Silent
to keep quiet, to be silent to refrain from speaking or talking
MAT 20:31 · MAT 26:63 · MRK 3:4 · MRK 9:34 · MRK 10:48 · MRK 14:61 · LUK 1:20 · LUK 19:40 · ACT 18:9
33.118 · Communication · Keep Silent
to not be able to speak to lose or not have the ability to speak It is possible that σιωπάω in LUK 1:20 means only ‘to say nothing’ or ‘to remain silent’ (33.117), in which case it would probably be better to reverse somewhat the order and translate ‘and you will not be able to speak but will remain silent until the day these things happen.’
14.24 · Physical Events and States · Events Involving Liquids and Dry Masses
to become calm, to become still (a figurative extension of meaning of σιωπάω[a] ‘to be silent,’ 33.117) the process of becoming calm after a storm In a number of languages it is not possible to translate σιωπάω[c] literally as ‘be still’ since this might imply continue to remain still. Since there is a change in state, it may be necessary to say become still or cease to be stormy.
