'Bowed Their Heads' in the Bible

And the people believed: and when they heard that the LORD had visited the children of Israel, and that he had looked upon their affliction, then they bowed their heads and worshipped.

that ye shall say, It is a sacrifice of passover to Jehovah, who passed over the houses of the children of Israel in Egypt when he smote the Egyptians and delivered our houses. And the people bowed their heads and worshipped.
