Isaiah 26:1-4

In that day this song will be sung in the land of Judah: “We have a strong city; He sets up salvation as walls and ramparts. “Open the gates, that the righteous nation may enter, The one that remains faithful and trustworthy. “You will keep in perfect and constant peace the one whose mind is steadfast [that is, committed and focused on You—in both inclination and character], Because he trusts and takes refuge in You [with hope and confident expectation]. “Trust [confidently] in the LORD forever [He is your fortress, your shield, your banner], For the LORD GOD is an everlasting Rock [the Rock of Ages].
