'Calm' in the Bible

Because of this the earth will quake, and all who live in it will mourn. The whole earth will rise like the River Nile, it will surge upward and then grow calm, like the Nile in Egypt.

The sovereign Lord who commands armies will do this. He touches the earth and it dissolves; all who live on it mourn. The whole earth rises like the River Nile, and then grows calm like the Nile in Egypt.
