'Little' in the Bible

In the same sense, the tongue is a small part of the body, and yet it boasts of great things.See [by comparison] how great a forest is set on fire by a small spark!

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].
