'Floodwaters' in the Bible

And this shall happen: on that day, Yahweh will thresh from the floodwaters of the Euphrates to the wadi of Egypt, and [as for] you, you will be gathered one by one, sons of Israel.

I will make justice the measuring line, fairness the plumb line; hail will sweep away the unreliable refuge, the floodwaters will overwhelm the hiding place.
