'Rod' in the Bible

In the lips of the intelligent is wisdom found, And a rod is for the back of him who is lacking understanding.

Whoso is sparing his rod is hating his son, And whoso is loving him hath hastened him chastisement.

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

Whoso is sowing perverseness reapeth sorrow, And the rod of his anger weareth out.

Folly is bound up in the heart of a youth, The rod of chastisement putteth it far from him.

Withhold not from a youth chastisement, When thou smitest him with a rod he dieth not.

Thou with a rod smitest him, And his soul from Sheol thou deliverest.

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

A rod and reproof give wisdom, And a youth let away is shaming his mother.
