'Rod' in the Bible

In the lips of an intelligent man 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 fool's mouth is a rod of pride; but the lips of the wise shall preserve them.

He that soweth unrighteousness shall reap iniquity, and the rod of his wrath shall have an end.

Folly is bound in the heart of a child; 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 Sheol.

A whip for the horse, a bridle for the ass, and a rod for the back of fools.

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