The Watering Can
When thou vowest a vow unto God, defer not to pay it; for he hath no pleasure in fools: pay that which thou hast vowed. Better is it that thou shouldest not vow, than that thou shouldest vow and not pay.
Ecclesiastes 5:4-5 KJV
This is an original fictional illustration, not a historical report or an added Bible event.
Theo promised to water the classroom plant before going home. When the bell rang, he hurried toward the door with his friends.
Then he remembered the empty watering can. He went back, gave the plant the right amount of water, and put the can away. His friends were still waiting when he returned.
Ecclesiastes teaches us to take promises to God seriously. It also reminds us not to speak carelessly about what we will do. Theo's small promise needed an action, not just a good memory.
Be careful with your yes. Ask for help when you cannot keep a commitment, and tell the truth promptly.
For the grown-up reading along
Ecclesiastes warns against careless vows made to God. The direct subject is reverent speech before Him. The broader concern for truthful commitments can inform ordinary promises without treating every casual plan as a sacred vow.
