Ecclesiastes 10:10-12

Douay-Rheims 1899 American Edition

¹⁰ If the iron be blunt, and be not as before, but be made blunt, with much labour it shall be sharpened: and after industry shall follow wisdom.

¹¹ If a serpent bite in silence, he is nothing better that backbiteth secretly.

¹² The words of the mouth of a wise man are grace: but the lips of a fool shall throw him down headlong.
