'Rod' in the Bible

On the lips of one who has understanding, wisdom is found, but a rod [is] for the back of one who lacks {sense}.

He who withholds his rod hates his child, but he who loves him {gives him} discipline.

In the mouth of a fool is the rod of pride, but the lips of the wise preserve them.

He who sows injustice will reap calamity, and the rod of his anger will fail.

Folly is bound up in the heart of a boy; [the] rod of discipline will drive it from him.

Do not withhold discipline from a child, if you will beat him with the rod, he will not die.

As for you, with the rod you shall beat him, and his life you will save from Sheol.

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

As for a rod and reproof, they will give wisdom, but a neglected child is disgraced [by] his mother.
