Bit

The curb put into the mouths of horses to restrain them. The Hebrew word (metheg) so rendered in Ps 32:9 is elsewhere translated “bridle” (2 Kgs 19:28; Prov 26:3; Isa 37:29). Bits were generally made of bronze or iron, but sometimes also of gold or silver. In Jas 3:3 the Authorized Version translates the Greek word by “bits,” but the Revised Version by “bridles.”
