Isaiah 26:1-4

In that day shall this song be sung in the land of Judah: We have a strong city; salvation will he appoint for walls and bulwarks. Open ye the gates, that the righteous nation which keepeth faith may enter in. Thou wilt keep him in perfect peace, whose mind is stayed on thee; because he trusteth in thee. Trust ye in Jehovah for ever; for in Jehovah, even Jehovah, is an everlasting rock.
