'Once' in the Bible

They answered once more and said, "Let the king tell the dream to his servants and we will make the explanation known."

Then the iron, the clay, the bronze, the silver and the gold {all at once} broke into pieces and they became like chaff from the summer threshing floor, and the wind carried them away and any trace of them could not be found. But the stone that struck the statue became a great mountain and it filled the whole earth.
