'Single' in the Bible

Then Pharaoh inquired and discovered that not a single one of the livestock of Israel had died, but Pharaoh's heart was stubborn and he would not let the people go.

A single law exists for the native and the alien who resides among you."

The water returned, covering the chariots and the horsemen of Pharaoh's entire army that had pursued the Israelis into the sea. Not a single one of them remained.

I won't drive them out before you in a single year, so that the land does not become desolate and so that wild animals do not overrun you.
