The Hebrews reckoned two evenings of each day, as appears from Ex. 16:12; 30:8; 12:6 (marginal note); Lev. 23:5 (marginal note Revised Version, “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.
