Ensign

(1.) Heb. 'oth, a military standard, especially of a single
tribe (Num. 2:2). Each separate tribe had its own "sign" or
"ensign."

(2.) Heb. nes, a lofty signal, as a column or high pole (Num.
21:8, 9); a standard or signal or flag placed on high mountains
to point out to the people a place of rendezvous on the
irruption of an enemy (Isa. 5:26; 11:12; 18:3; 62:10; Jer. 4:6,
21; Ps. 60:4). This was an occasional signal, and not a military
standard. Elevation and conspicuity are implied in the word.

(3.) The Hebrew word "degel" denotes the standard given to
each of the four divisions of the host of the Israelites at the
Exodus (Num. 1:52; 2:2; 10:14). In Cant. 2:4 it is rendered
"banner." We have no definite information as to the nature of
these military standards. (See BANNER T0000433.)
