Ecclesiastes 10:8-11

When you dig a well, you might fall in. When you demolish an old wall, you could be bitten by a snake. When you work in a quarry, stones might fall and crush you. When you chop wood, there is danger with each stroke of your ax. Using a dull ax requires great strength, so sharpen the blade. That’s the value of wisdom; it helps you succeed. If a snake bites before you charm it, what’s the use of being a snake charmer?
