'Plans' in the Bible

For who [limited by human wisdom] knows what is good for man during his lifetime, during the few days of his futile life? He spends them like a shadow [staying busy, but achieving nothing of lasting value]. For who can tell a man what will happen after him [to his work, his treasure, his plans] under the sun [after his life is over]?

Whatever your hand finds to do--do [it] with [all] your might; for in Sheol--where you are going--no one works, plans, knows, or thinks about anything.
