Exodus 7:19

19 ADONAI said to Moshe, "Say to Aharon, 'Take your staff, reach out your hand over the waters of Egypt, over their rivers, canals, ponds and all their reservoirs, so that they can turn into blood. There will be blood throughout the whole land of Egypt, even in the wooden buckets and stone jars.'"

Exodus 7:19 Meaning and Commentary

Exodus 7:19

And the Lord spake unto Moses
Pharaoh still being obstinate, and refusing to let the people go:

say unto Aaron, take thy rod, and stretch out thine hand upon the
waters of Egypt;
upon all of them in general, what were in the river Nile, or derived from it, as follows:

upon their streams;
the seven streams of the river Nile, (See Gill on Isaiah 11:15).

upon their rivers;
the canals that were cut out of the river Nile, for the watering of their fields and gardens, for they had no other river:

and upon their ponds, and upon all their pools of waters;
which were dug near the river, or to which pipes were laid to convey the water thither:

that they may become blood;
and so not fit to drink:

and that there may be blood throughout all the land of Egypt,
both in vessels of wood, and in vessels of stone;
in which water were kept in private houses, fetched from the river for the use of families; all which were to be turned into blood everywhere, in all parts of the land, and in all places mentioned, immediately upon Aaron's taking his rod, and smiting the waters with it in that part of the river that was before him.

Exodus 7:19 In-Context

17 so ADONAI says, "This will let you know that I am ADONAI": I will take the staff in my hand and strike the water in the river, and it will be turned into blood.

18 The fish in the river will die, the river will stink and the Egyptians won't want to drink water from the river.'"

19 ADONAI said to Moshe, "Say to Aharon, 'Take your staff, reach out your hand over the waters of Egypt, over their rivers, canals, ponds and all their reservoirs, so that they can turn into blood. There will be blood throughout the whole land of Egypt, even in the wooden buckets and stone jars.'"

20 Moshe and Aharon did exactly what ADONAI had ordered. He raised the staff and, in the sight of Pharaoh and his servants, struck the water in the river; and all the water in the river was turned into blood.

21 The fish in the river died, and the river stank so badly that the Egyptians couldn't drink its water. There was blood throughout all the land of Egypt.
