Psalms 32:9

For he spoke, and they were made; he commanded, and they were created.

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.

Don’t be like the horse, or like the mule, which have no understanding, who are controlled by bit and bridle, or else they will not come near to you.
