19 And the LORD spake unto Moses, Say unto Aaron, Take thy rod, and stretch out thine hand upon the waters of Egypt, upon their streams, upon their rivers, and upon their ponds, and upon all their pools of water, that they may become blood; and that there may be blood throughout all the land of Egypt, both in vessels of wood, and in vessels of stone.
18 And it came to pass, when the priests that bare the ark of the covenant of the LORD were come up out of the midst of Jordan, and the soles of the priests' feet were lifted up unto the dry land, that the waters of Jordan returned unto their place, and flowed over all his banks, as they did before.
19 And say unto the people of the land, Thus saith the Lord GOD of the inhabitants of Jerusalem, and of the land of Israel; They shall eat their bread with carefulness, and drink their water with astonishment, that her land may be desolate from all that is therein, because of the violence of all them that dwell therein.
