What's the "een" in Halloween?
late 14c., "one to whom divine revelations are made," agent noun from see (v.). Originally rendering Latin videns, Greek bleptor (from Hebrew roeh) in Bible translations (e.g. I Kings ix:9). Literal sense of "one who sees" is attested from early 15c.
a name sometimes applied to the prophets because of the visions granted to them. It is first found in 1 Sam. 9:9. It is afterwards applied to Zadok, Gad, etc. (2 Sam. 15:27; 24:11; 1 Chr. 9:22; 25:5; 2 Chr. 9:29; Amos 7:12; Micah 3:7). The "sayings of the seers" (2 Chr. 33:18, 19) is rendered in the Revised Version "the history of Hozai" (marg., the seers; so the LXX.), of whom, however, nothing is known. (See PROPHET.)
