'Perpetually' in the Bible

May Joab and his descendants be perpetually guilty of their shed blood, but may the Lord give perpetual peace to David, his descendants, his family, and his dynasty."

And the LORD said unto him, I have heard thy prayer and thy supplication, that thou hast made before me: I have hallowed this house, which thou hast built, to put my name there for ever; and mine eyes and mine heart shall be there perpetually.
