'Ahead' in the Bible

Take counsel together, but it will all be for nothing; go ahead and talk, but it will all be for nothing, for God is with us."

Who decreed this from the beginning, so we could know? Who announced it ahead of time, so we could say, 'He's correct'? Indeed, none of them decreed it! Indeed, none of them announced it! Indeed, no one heard you say anything!

he enters [into] peace; they will rest on their beds, walking straight ahead of him.
