from selas, "brightness" (the Heb. words are yareach, "wandering," and lebanah, "white"), occurs in Mat 24:29, Mar 13:24, Luk 21:25, Act 2:20, 1Co 15:41, Rev 6:12, Rev 8:12, Rev 12:1, Rev 21:23. In Rev 12:1, "the moon under her feet" is suggestive of derived authority, just as her being clothed with the sun is suggestive of supreme authority; everything in the symbolism of the passage centers in Israel. In Rev 6:12 the similar symbolism of the sun and "moon" is suggestive of the supreme authority over the world, and of derived authority, at the time of the execution of Divine judgments upon nations at the close of the present age.
<2,,3561, neomenia>
or noumeniua, denoting "a new moon" (neos, "new," men, "a month:" see MONTH), is used in Col 2:16, of a Jewish festival. Judaistic tradition added special features in the liturgy of the synagogue in connection with the observance of the first day of the month, the new "moon" time.
In the OT the RV has "new moon" for AV, "month" in Num 29:6, 1Sa 20:27, Hos 5:7. For the connection with feast days see Lev 23:24, Num 10:10, Num 29:1, Psa 81:3.
