Sirach 30:1-6

1 He that loveth his son causeth him oft to feel the rod, that he may have joy of him in the end.

2 He that chastiseth his son shall have joy in him, and shall rejoice of him among his acquaintance.

3 He that teacheth his son grieveth the enemy: and before his friends he shall rejoice of him.

4 Though his father die, yet he is as though he were not dead: for he hath left one behind him that is like himself.

5 While he lived, he saw and rejoiced in him: and when he died, he was not sorrowful.

6 He left behind him an avenger against his enemies, and one that shall requite kindness to his friends.
