A subset of verses about Being Still. NIV.

Come and see the works of the LORD, the desolations he has brought on the earth. He makes wars cease to the ends of the earth; he breaks the bow and shatters the spear, he burns the shields with fire. "Be still, and know that I am God; I will be exalted among the nations, I will be exalted in the earth."

Psalm 46:8-10

You answer us with awesome deeds of righteousness, O God our Savior, the hope of all the ends of the earth and of the farthest seas, who formed the mountains by your power, having armed yourself with strength, who stilled the roaring of the seas, the roaring of their waves, and the turmoil of the nations.

Psalm 65:5-7

Then they cried out to the LORD in their trouble, and he brought them out of their distress. He stilled the storm to a whisper; the waves of the sea were hushed. They were glad when it grew calm, and he guided them to their desired haven.

Psalm 107:28-30

My heart is not proud, O LORD , my eyes are not haughty; I do not concern myself with great matters or things too wonderful for me. But I have stilled and quieted my soul; like a weaned child with its mother, like a weaned child is my soul within me.

Psalm 131:1-2
