Isaiah 26:4

2 Open the gates so a righteous nation may enter— one that remains faithful.

3 You will keep in perfect peace the steadfast of mind, because he trusts in You.

Trust in the LORD forever, because GOD the LORD is the Rock eternal.

5 For He has humbled those who dwell on high; He lays the lofty city low. He brings it down to the ground; He casts it into the dust.

6 Feet trample it down— the feet of the oppressed, the steps of the poor.

Do read the surrounding verses too, because the context often says more than a single verse.
