'Everlasting' in the Bible

Art thou not from everlasting, O LORD my God, mine Holy One? we shall not die. O LORD, thou hast ordained them for judgment; and, O mighty God, thou hast established them for correction.

He stood, and measured the earth: he beheld, and drove asunder the nations; and the everlasting mountains were scattered, the perpetual hills did bow: his ways are everlasting.
