Instruct thy son, and he shall refresh thee, and shall give delight to thy soul.
The rod and reproof give wisdom: but the child that is left to his own will bringeth his mother to shame.
He that spareth the rod hateth his son: but he that loveth him correcteth him betimes.
A wise son maketh the father glad: but a foolish son is the sorrow of his mother.
Folly is bound up in the heart of a child, and the rod of correction shall drive it away.
Chastise thy son, despair not: but to the killing of him set not thy soul.
