Exodus 7:19

19 And Jehovah said unto Moses, Say unto Aaron, Take thy rod, and stretch out thy hand over the waters of Egypt, over their rivers, over their streams, and over their pools, and over all their ponds of water, that they may become blood; and there shall be blood throughout all the land of Egypt, both in vessels of wood and in vessels of stone.

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 Thus saith Jehovah, In this thou shalt know that I am Jehovah: behold, I will smite with the rod that is in my hand upon the waters which are in the river, and they shall be turned to blood.
18 And the fish that are in the river shall die, and the river shall become foul; and the Egyptians shall loathe to drink water from the river.
19 And Jehovah said unto Moses, Say unto Aaron, Take thy rod, and stretch out thy hand over the waters of Egypt, over their rivers, over their streams, and over their pools, and over all their ponds of water, that they may become blood; and there shall be blood throughout all the land of Egypt, both in vessels of wood and in vessels of stone.
20 And Moses and Aaron did so, as Jehovah commanded; and he lifted up the rod, and smote the waters that were in the river, in the sight of Pharaoh, and in the sight of his servants; and all the waters that were in the river were turned to blood.
21 And the fish that were in the river died; and the river became foul, and the Egyptians could not drink water from the river; and the blood was throughout all the land of Egypt.
