American Standard Version (ASV):
Be ye not as the horse, or as the mule, which have no understanding; Whose trappings must be bit and bridle to hold them in, [Else] they will not come near unto thee.
King James Version (KJV):
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.
