Exodus 8:17
This they did, and when Aaron stretched out his hand with his staff and struck the dust of the earth, gnats came upon man and beast. All the dust of the earth turned into gnats throughout the land of Egypt.
This they did,

Moses and Aaron obeyed the Lord exactly, carrying out His command without delay. Their faithfulness displayed trust in God’s purpose even as Egypt resisted His word.

Exo 7:6 So Moses and Aaron did just as the LORD had commanded them.
Exo 12:28 And the Israelites went and did just what the LORD commanded…
Exo 39:42-43 The Israelites had done all the work just as the LORD…

and when Aaron stretched out his hand with his staff

Aaron acted as God’s appointed representative, and the staff visibly marked the divine authority behind the sign. The Lord was revealing that Egypt’s gods, magicians, and rulers possessed no power equal to His.

Exo 7:19 Take your staff and stretch out your hand…
Exo 7:20 Moses and Aaron did just as the LORD had commanded;…
Exo 14:16 And as for you, lift up your staff and stretch out your hand…

and struck the dust of the earth,

The ground from which man was formed became the instrument of judgment upon rebellious Egypt. God, who gives life from the dust, also rules every part of creation and can turn its ordinary elements into a source of affliction.

Psa 18:42 I ground them as dust in the face of the wind;…
2Sa 22:43 I ground them as the dust of the earth; I crushed…
Gen 3:19 By the sweat of your brow you will eat your bread,…

gnats came upon man and beast.

No class of Egyptian society and no household escaped the plague. The suffering of both people and animals exposed the helplessness of Pharaoh’s kingdom before the Lord.

Psa 105:31 He spoke, and insects swarmed—gnats throughout their country…
Psa 78:45 He sent swarms of flies that devoured them…

All the dust of the earth turned into gnats

The plague spread with supernatural abundance, demonstrating that God’s power extended over the whole land. What had been dust underfoot became an inescapable sign of divine judgment.

Gen 2:7 Then the LORD God formed man from the dust of the ground…
Gen 13:16 I will make your offspring like the dust of the earth…
Gen 28:14 Your descendants will be like the dust of the earth,…

throughout the land of Egypt.

Egypt’s strength, wealth, and false worship could not shield it from the God of Israel. The Lord’s judgments humbled a mighty nation and prepared the way for the deliverance of His people.

Exo 11:6 Then a great cry will go out over all the land of Egypt.…
Exo 12:30 During the night Pharaoh got up—he and all his officials…
Psa 105:27 They performed His miraculous signs among them,…

He was a man of some knowledge in his own eyes, and dared to say that in the Eucharist there is only a sacrament and not the fact[718] of the sacrament, that is, mere sanctification and not the truth of the Body. On this subject he was often addressed by Malachy in secret, but in vain; and finally he was called before a public assembly, the laity however being excluded, in order that if it were

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,
