FROM STRONG’S HEBREW DICTIONARY (1890)

Strong’s Hebrew Dictionary (1890) — public domain, printed whole.

nacac naw-sas' — a primitive root; to gleam from afar, i.e. to be conspicuous as a signal; or rather perhaps a denominative from 5251 (and identical with 5263, through the idea of a flag as fluttering in the wind); to raise a beacon:--lift up as an ensign.
