'Rod' in the Bible

In the lips of him that hath understanding wisdom is found: but a rod is for the back of him that is void of understanding.

He that spareth his rod hateth his son: but he that loveth him chasteneth him betimes.

In the mouth of the foolish is a rod of pride: but the lips of the wise shall preserve them.

He that soweth iniquity shall reap vanity: and the rod of his anger shall fail.

Foolishness is bound in the heart of a child; but the rod of correction shall drive it far from him.

Withhold not correction from the child: for if thou beatest him with the rod, he shall not die.

Thou shalt beat him with the rod, and shalt deliver his soul from hell.

A whip for the horse, a bridle for the ass, and a rod for the fool's back.

The rod and reproof give wisdom: but a child left to himself bringeth his mother to shame.
