'Eternity' in the Bible

For to us a Child shall be born, to us a Son shall be given;And the government shall be upon His shoulder,And His name shall be called Wonderful Counselor, Mighty God,Everlasting Father, Prince of Peace.

Israel has been saved by the LordWith an everlasting salvation;You will not be put to shame or humiliatedfor all eternity.

For the high and exalted OneHe who inhabits eternity, Whose name is Holy says this,“I dwell on the high and holy place,But also with the contrite and humble in spiritIn order to revive the spirit of the humbleAnd to revive the heart of the contrite [overcome with sorrow for sin].
