And it shall come to pass, if they will not believe also these two signs, neither hearken unto thy voice, that thou shalt take of the water of the river, and pour it upon the dry land: and the water which thou takest out of the river shall become blood upon the dry land.

But if they will not even believe these two signs, nor hear thy voice: take of the river water, and pour it out upon the dry land, and whatsoever thou drawest out of the river shall be turned into blood.

And it shall come to pass, if they will not believe also those two signs, neither hearken unto thy voice, that thou shalt take of the water of the river, and pour it on the dry land; and the water that thou takest out of the river shall become blood upon the dry land.

And it hath come to pass, if they do not give credence even to these two signs, nor hearken to thy voice, that thou hast taken of the waters of the River, and hast poured on the dry land, and the waters which thou takest from the River have been, yea, they have become, blood on the dry land.'

And if they have no faith even in these two signs and will not give ear to your voice, then you are to take the water of the Nile and put it on the dry land: and the water you take out of the river will become blood on the dry land.

But if they will not believe even these two signs, and they will not listen to your voice: take from the water of the river, and pour it upon the dry land, and whatever you will have drawn from the river will be turned into blood."

Erit autem, si non crediderint etiam duobus signis istis, neque obedierint voci tuae, tunc accipies ex aquis fluvii, et effundes in aridam: et erunt aquae quas sumpseris e fluvio, erunt inquam sanguis in arida.

And it shall come to pass, if they will not believe also these two signs, neither hearken unto thy voice, that thou shalt take of the (c) water of the river, and pour [it] upon the dry [land]: and the water which thou takest out of the river shall become blood upon the dry [land].
(c) Because these three signs should be sufficient witnesses to prove that Moses should deliver God's people.

And it shall come to pass, if they will not believe also these two signs,.... Performed before their eyes; for these were done over again when Moses came into Egypt to the Israelites, and yet some of them might still remain unbelievers to his commission, and so to the voice of these signs, which loudly called for their faith:
neither hearken unto thy voice; affirming he came from God, and was sent to be the deliverer of them:
that thou shalt take of the water of the river; of the river Nile, when he should come into Egypt; wherefore Josephus (q) is mistaken when he intimates that this was done at the same time with the other signs; and was water he took near at hand and poured on the ground: but Philo (r) truly refers this to Egypt, where it was done, as it ought to be:
and pour it upon the dry land, and the water which thou takest out of the river shall become blood upon the dry land; by which it would appear how easily the Lord could destroy the land of Egypt, and make it a barren land, whose fertility was owing to the overflow of the river Nile as a means; and this would be a specimen also of what he would do hereafter, in turning the waters of the river into blood, thereby avenging the blood of innocent babes drowned there by the Egyptians.

take of the water of the river--Nile. Those miracles, two of which were wrought then, and the third to be performed on his arrival in Goshen, were at first designed to encourage him as satisfactory proofs of his divine mission, and to be repeated for the special confirmation of his embassy before the Israelites.

The Third Sign. - If the first two signs should not be sufficient to lead the people to believe in the divine mission of Moses, he was to give them one more practical demonstration of the power which he had received to overcome the might and gods of Egypt. He was to take of the water of the Nile (the river, Genesis 41:1) and pour it upon the dry land, and it would become blood (the second והיוּ is a resumption of the first, cf. Exodus 12:41). The Nile received divine honours as the source of every good and all prosperity in the natural life of Egypt, and was even identified with Osiris (cf. Hengstenberg, Egypt and the Books of Moses, p. 109 transl.). If Moses therefore had power to turn the life-distributing water of the Nile into blood, he must also have received power to destroy Pharaoh and his gods. Israel was to learn this from the sign, whilst Pharaoh and the Egyptians were afterwards to experience this might of Jehovah in the form of punishment (Exodus 7:15.). Thus Moses as not only entrusted with the word of God, but also endowed with the power of God; and as he was the first God-sent prophet, so was he also the first worker of miracles, and in this capacity a type of the Apostle of our profession (Hebrews 3:1), even the God-man, Christ Jesus.
