'Vapor' in the Bible

You, indeed, have made my days short in length,and my life span as nothing in Your sight.Yes, every mortal man is only a vapor.Selah

You discipline a man with punishment for sin,consuming like a moth what is precious to him;every man is only a vapor.Selah

Men are only a vapor;exalted men, an illusion.Weighed in the scales, they go up;together they are less than a vapor.
