Exodus 7:20
Moses and Aaron did just as the LORD had commanded; in the presence of Pharaoh and his officials, Aaron raised the staff and struck the water of the Nile, and all the water was turned to blood.
Moses and Aaron did just as the LORD had commanded;

Their obedience displayed faith in God’s word before Israel’s oppressors. Neither Moses nor Aaron altered the command to make it more acceptable to Pharaoh or less threatening to Egypt. Their submission stands in contrast to Pharaoh’s hardened resistance and points forward to Christ, who humbled Himself and became obedient to the Father even unto death.

Exo 12:28 And the Israelites went and did just what the LORD commanded…
Lev 8:36 So Aaron and his sons did everything the LORD had commanded…
Exo 40:16 Moses did everything just as the LORD had commanded him.

in the presence of Pharaoh and his officials,

God performed the sign openly before Egypt’s ruler and court. Pharaoh was regarded as divine in Egyptian religion, yet he and his officials stood powerless before the God of Israel. The plague was a public declaration that the LORD alone rules kings, nations, and the forces of nature.

Exo 11:10 Moses and Aaron did all these wonders before Pharaoh…
Exo 11:3 And the LORD gave the people favor in the sight of the Egyptians…
Exo 9:13 Then the LORD said to Moses, “Get up early in the morning…

Aaron raised the staff and struck the water of the Nile,

The staff, entrusted to Moses and Aaron by God, represented divine authority exercised through human servants. The Nile was Egypt’s source of irrigation, transportation, food, and economic strength. By striking its waters, the LORD judged Egypt’s confidence in its river and its gods, including Hapi, who was associated with the Nile’s annual life-giving flood.

Num 20:8-11 Take the staff and assemble the congregation.…
2Ki 2:14 Then he took the cloak of Elijah and struck the waters.…
Exo 14:16 And as for you, lift up your staff and stretch out your hand…

and all the water was turned to blood.

The Nile’s waters became a sign of death rather than life, bringing judgment upon the land that had shed the blood of Israelite infants in its river. The plague began God’s direct assault on Egypt’s false worship and announced that Israel’s deliverance would come through His mighty hand. Blood also points to the seriousness of sin and judgment, while anticipating the blood of Christ, by which God provides forgiveness and redemption for His people.

Psa 105:29 He turned their waters to blood and caused…
Psa 78:44 He turned their rivers to blood, and from their streams…
Rev 16:3-4 And the second angel poured out his bowl into the sea…

The History of the Prophetic Sermons, Epistles, and Apocalypses
[Sidenote: Real character and aims of the prophets] To understand and rightly interpret the prophetic writings of the Old Testament it is necessary to cast aside a false impression as to the character of the prophets which is widely prevalent. They were not foretellers, but forth-tellers. Instead of being vague dreamers, in imagination living far in the distant future, they were most emphatically men of their own times, enlightened and devoted patriots, social and ethical reformers, and spiritual

Letter Lxxxv. To Paulinus.
Paulinus had asked Jerome two questions, (1) how can certain passages of scripture (Exod. vii. 13; Rom. ix. 16) be reconciled with Free Will? and (2) Why are the children of believers said to be holy (1 Cor. vii. 14) apart from baptismal grace? For the first of these questions Jerome refers Paulinus to his version (newly made) of Origen's treatise, On First Principles. For the second he quotes the explanation of Tertullian. Written in 400 a.d. 1. Your words urge me to write to you but your eloquence

The Hardening in the Sacred Scripture.
"He hath hardened their heart."-- John xii. 40. The Scripture teaches positively that the hardening and "darkening of their foolish heart" is a divine, intentional act. This is plainly evident from God's charge to Moses concerning the king of Egypt: "Thou shalt speak all that I command thee; and I will harden Pharaoh's heart, and multiply My signs and wonders in the land of Egypt. But Pharaoh shall not harken unto you, and I will lay My hand upon Egypt, and the Egyptians shall know that I am the

Exposition of Chap. Iii. (ii. 28-32. )
Ver. 1. "And it shall come to pass, afterwards, I will pour out My Spirit upon all flesh; and your sons and your daughters shall prophesy; your old men shall dream dreams, and your young men shall see visions." The communication of the Spirit of God was the constant prerogative of the Covenant-people. Indeed, the very idea of such a people necessarily requires it. For the Spirit of God is the only inward bond betwixt Him and that which is created; a Covenant-people, therefore, without such an inward

Exodus
The book of Exodus--so named in the Greek version from the march of Israel out of Egypt--opens upon a scene of oppression very different from the prosperity and triumph in which Genesis had closed. Israel is being cruelly crushed by the new dynasty which has arisen in Egypt (i.) and the story of the book is the story of her redemption. Ultimately it is Israel's God that is her redeemer, but He operates largely by human means; and the first step is the preparation of a deliverer, Moses, whose parentage,
