Ecclesiastes 10:8-11
Ecclesiastes 10:8-11 NIV
Whoever digs a pit may fall into it; whoever breaks through a wall may be bitten by a snake. Whoever quarries stones may be injured by them; whoever splits logs may be endangered by them. If the ax is dull and its edge unsharpened, more strength is needed, but skill will bring success. If a snake bites before it is charmed, the charmer receives no fee.
