One of Solomon’s favorite words in Ecclesiastes is the word, “vanity.” He uses it 38 times. The Hebrew word is “hevel” which means, “emptiness, futility, vapor.”
Therfore, whatever disappears quickly, leaves nothing behind, and does not satisfy is considered to be vanity. Never allow vanity to consume your life because things that are vane will not last and have no real value. Stay faithful and do not allow material items become who you are.
