'Disappears' in the Bible

Yet you do not know [the least thing] about what may happen in your life tomorrow. [What is secure in your life?] You are merely a vapor [like a puff of smoke or a wisp of steam from a cooking pot] that is visible for a little while and then vanishes [into thin air].

The world is passing away, and with it its lusts [the shameful pursuits and ungodly longings]; but the one who does the will of God and carries out His purposes lives forever.
