The First Plague: Water Turned to Blood
14 Then the Lord said to Moses, “Pharaoh’s heart is hardened; he refuses to let the people go. 15 Go to Pharaoh in the morning, as he is going out to the water; stand by at the river bank to meet him, and take in your hand the staff that was turned into a snake. 16 Say to him, ‘The Lord, the God of the Hebrews, sent me to you to say, “Let my people go, so that they may worship me in the wilderness.” But until now you have not listened. 17 Thus says the Lord, “By this you shall know that I am the Lord.” See, with the staff that is in my hand I will strike the water that is in the Nile, and it shall be turned to blood. 18 The fish in the river shall die, the river itself shall stink, and the Egyptians shall be unable to drink water from the Nile.’” 19 The Lord said to Moses, “Say to Aaron, ‘Take your staff and stretch out your hand over the waters of Egypt—over its rivers, its canals, and its ponds, and all its pools of water—so that they may become blood; and there shall be blood throughout the whole land of Egypt, even in vessels of wood and in vessels of stone.’”
20 Moses and Aaron did just as the Lord commanded. In the sight of Pharaoh and of his officials he lifted up the staff and struck the water in the river, and all the water in the river was turned into blood, 21 and the fish in the river died. The river stank so that the Egyptians could not drink its water, and there was blood throughout the whole land of Egypt. 22 But the magicians of Egypt did the same by their secret arts; so Pharaoh’s heart remained hardened, and he would not listen to them, as the Lord had said. 23 Pharaoh turned and went into his house, and he did not take even this to heart. 24 And all the Egyptians had to dig along the Nile for water to drink, for they could not drink the water of the river.
25 Seven days passed after the Lord had struck the Nile.
Thanksgiving for Deliverance and Prayer for Help
To the leader. Of David. A Psalm.
1 I waited patiently for the Lord;
he inclined to me and heard my cry.
2 He drew me up from the desolate pit,
out of the miry bog,
and set my feet upon a rock,
making my steps secure.
3 He put a new song in my mouth,
a song of praise to our God.
Many will see and fear,
and put their trust in the Lord.
4 Happy are those who make
the Lord their trust,
who do not turn to the proud,
to those who go astray after false gods.
5 You have multiplied, O Lord my God,
your wondrous deeds and your thoughts toward us;
none can compare with you.
Were I to proclaim and tell of them,
they would be more than can be counted.
6 Sacrifice and offering you do not desire,
but you have given me an open ear.
Burnt offering and sin offering
you have not required.
7 Then I said, “Here I am;
in the scroll of the book it is written of me.
8 I delight to do your will, O my God;
your law is within my heart.”
9 I have told the glad news of deliverance
in the great congregation;
see, I have not restrained my lips,
as you know, O Lord.
10 I have not hidden your saving help within my heart,
I have spoken of your faithfulness and your salvation;
I have not concealed your steadfast love and your faithfulness
from the great congregation.
11 Do not, O Lord, withhold
your mercy from me;
let your steadfast love and your faithfulness
keep me safe forever.
12 For evils have encompassed me
my iniquities have overtaken me,
until I cannot see;
they are more than the hairs of my head,
and my heart fails me.
13 Be pleased, O Lord, to deliver me;
O Lord, make haste to help me.
14 Let all those be put to shame and confusion
who seek to snatch away my life;
let those be turned back and brought to dishonor
who desire my hurt.
15 Let those be appalled because of their shame
who say to me, “Aha, Aha!”
16 But may all who seek you
rejoice and be glad in you;
may those who love your salvation
say continually, “Great is the Lord!”
17 As for me, I am poor and needy,
but the Lord takes thought for me.
You are my help and my deliverer;
do not delay, O my God.
