I looked again and saw under the sun that the race [does] not [belong] to the swift, the battle [does] not [belong] to the mighty, food [does] not [belong] to the wise, wealth [does] not [belong] to the intelligent, and success [does] not [belong] to the skillful, for time and chance befalls all of them.

If the ax is blunt but one does not sharpen its edge, {he must exert more effort}, but the advantage of wisdom [is] it brings success.
