'Speechless' in the Bible

Now the hand of the Lord had been upon me in the evening, before the refugees came. And He opened my mouth at the time they came to me in the morning; so my mouth was opened and I was no longer speechless.

When he had spoken to me according to these words, I turned my face toward the ground and became speechless.

“What profit is the idol when its maker has carved it,Or an image, a teacher of falsehood?For its maker trusts in his own handiworkWhen he fashions speechless idols.
