mo'-ment (regha`, "a wink"; atomos, "an atom," stigme, "a point," parautika, immediately," "forthwith"): "Moment" is not used in Scripture for a division of time, but for an instant of time, as the wink or twinkling of the eye (Ex 33:5; Nu 16:21,45; La 4:6; 1Co 15:52), or for a short period of time (Job 20:5; Ps 30:5; Isa 26:20; 2Co 4:17). The division of the hour into sixty minutes was certainly known in Babylonia, and the Jews were made acquainted with it, at least during the captivity, but they do not seem to have adopted it very extensively.
