The verse in my post is Psalm 46:10 (NLT). Here are a few other Bible verses which also speak to me.
And he said, “Go forth, and stand upon the mount before the Lord.” And behold, the Lord passed by, and a great and strong wind rent the mountains, and broke in pieces the rocks before the Lord, but the Lord was not in the wind; and after the wind an earthquake, but the Lord was not in the earthquake; and after the earthquake a fire, but the Lord was not in the fire; and after the fire a still small voice. I Kings 19:11-12 (RSV)
"The Lord will fight for you. You just keep still." Exodus 14:14 (CEB)
"And this righteousness will bring peace. Yes, it will bring quietness and confidence forever." Isaiah 32:17 (NLT)
