Collar definition

(Heb. peh), means in Job 30:18 the mouth or opening of the garment that closes round the neck in the same way as a tunic (Ex. 39:23). The "collars" (Heb. netiphoth) among the spoils of the Midianites (Judg. 8:26; R.V., "pendants") were ear-drops. The same Hebrew word is rendered "chains" in Isa. 3:19.
