'Rod' in the Bible

On the lips of the discerning, wisdom is found,But a rod is for the back of him who lacks understanding.

He who withholds his rod hates his son,But he who loves him disciplines him diligently.

In the mouth of the foolish is a rod for his back,But the lips of the wise will protect them.

He who sows iniquity will reap vanity,And the rod of his fury will perish.

Foolishness is bound up in the heart of a child;The rod of discipline will remove it far from him.

Do not hold back discipline from the child,Although you strike him with the rod, he will not die.

You shall strike him with the rodAnd rescue his soul from Sheol.

A whip is for the horse, a bridle for the donkey,And a rod for the back of fools.

The rod and reproof give wisdom,But a child who gets his own way brings shame to his mother.
