'Calm' in the Bible

Say to him: Calm down and be quiet. Don’t be afraid or cowardly because of these two smoldering stubs of firebrands, the fierce anger of Rezin and Aram, and the son of Remaliah.

All the earth is calm and at rest;people shout with a ringing cry.

For this is what the LORD GOD, the Holy One of Israel, says: "In repentance and rest you will be saved; in staying calm and trusting will be your strength. But you refused.

For I am the Lord your God, who makes the sea calm when its waves are thundering: the Lord of armies is his name.
