'Vitality' in the Bible

I for my part will do this to you: I will inflict horror on you, consumption and fever, which diminish eyesight and drain away the vitality of life. You will sow your seed in vain because your enemies will eat it.

Moses was 120 years old when he died, but his eye was not dull nor had his vitality departed.

They bear fruit even when they are old; they are filled with vitality and have many leaves.
