⇒See the definition of collar in the KJV Dictionary
(1) (neTphah, plural neTphoth, literally, "drops," from naTaph, "to drop"). Jg 8:26 includes neTphoth among the spoils taken from the Midianites and Ishmaelites; the Revised Version (British and American) "pendants," the King James Version "collars." Qimchi at the place suggests "perfume-dropper."
(2) (peh, literally, "mouth"). In Job 30:18 the word is used to indicate the collar band, or hole of a robe, through which the head was inserted. Job, in describing his suffering and writhing, mentions the disfiguring of his garment, and suggests that the whole thing feels as narrow or close-fitting as the neckband, or perhaps that in his fever and pains he feels as if the neckband itself is choking him.

(3) (tsinoq, Jer 29:26, "stocks"; the Revised Version (British and American) "shackles," which see; the Revised Version, margin "collar"). An instrument of torture or punishment.
