Psalms 32:9

Be not like a horse or a mule , without understanding , which must be curbed with bit and bridle , or it will not stay near you.

Do not be like the horse or the mule, which have no understanding but must be controlled by bit and bridle or they will not come to you.

Be ye not as the horse, or as the mule, which have no understanding : whose mouth must be held in with bit and bridle, lest they come near unto thee.
