'We Have Sinned' in the Bible

And they rose up early in the morning and gat them up into the top of the mountain, saying, "Lo, we be here, and will go up unto the place of which the LORD said, for we have sinned."

And the people came to Moses, and said, "We have sinned, for we have spoken against the LORD and against thee: make intercession to the LORD, that he take away the serpents from us." And Moses made intercession for the people.
