For what is your life? It is even a vapour, that appeareth for a little time, and then vanisheth away. For that ye ought to say, If the Lord will, we shall live, and do this, or that.
If the iron be blunt, and he do not whet the edge, then must he put to more strength: but wisdom is profitable to direct.
Commit thy works unto the Lord, and thy thoughts shall be established.
