'Rod' in the Bible

In the lips of him that hath discernment 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 for his pride; But the lips of the wise shall preserve them.

He that soweth iniquity shall reap calamity; And the rod of his wrath shall fail.

Foolishness is bound up 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 beat him with the rod, he will 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 causeth shame to his mother.
