Three Hebrew words are thus rendered in the Authorized Version.

Heb. mahsom' signifies a muzzle or halter or bridle, by which the rider governs his horse (Ps.39:1).

Me'theg , rendered also "bit" in Psalms 32:9 , which is its proper meaning. Found in 2 Kings 19:28 , where the restraints of God's providence are metaphorically styled his "bridle" and "hook." God's placing a "bridle in the jaws of the people" ( Isaiah 30:28 ; 37:29 ) signifies his preventing the Assyrians from carrying out their purpose against Jerusalem.

Another word, re'sen , was employed to represent a halter or bridle-rein, as used Psalms 32:9 ; Isaiah 30:28 . In Job 30:11 the restraints of law and humanity are called a bridle.
