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