'Speechless' in the Bible

He watches over his holy ones, but the wicked are made speechless in the darkness, for it is not by one's own strength that one prevails.

"When this happens," says the Lord, "the king and his officials will lose their courage. The priests will be struck with horror, and the prophets will be speechless in astonishment."

The one who says to wood, 'Wake up!' is as good as dead -- he who says to speechless stone, 'Awake!' Can it give reliable guidance? It is overlaid with gold and silver; it has no life's breath inside it.

But the Lord is in his majestic palace. The whole earth is speechless in his presence!"
