Dict: easton - Evening

easton:

Evening @ the period following sunset with which the Jewish day began kjv@Genesis:1:5; kjv@Mark:13:35). The Hebrews reckoned two evenings of each day, as appears from kjv@Exodus:16:12: 30:8; 12:6 (marg.); kjv@Leviticus:23:5 (marg. R.V., "between the two evenings"). The "first evening" was that period when the sun was verging towards setting, and the "second evening" the moment of actual sunset. The word "evenings" in kjv@Jeremiah:5:6 should be "deserts" (marg. R.V.).
