Sirach 30:8-10

Douay-Rheims 1899 American Edition

⁸ A horse not broken becometh stubborn, and a child left to himself will become headstrong.

⁹ Give thy son his way, and he shall make thee afraid: play with him, and he shall make thee sorrowful.

¹⁰ Laugh not with him, lest thou have sorrow, and at the last thy teeth be set on edge.
