Exodus 8:21
But if you will not let My people go, I will send swarms of flies upon you and your officials and your people and your houses. The houses of the Egyptians and even the ground where they stand will be full of flies.
But if you refuse to let My people go
This phrase is a direct challenge to Pharaoh's authority, highlighting the ongoing struggle between God's will and human obstinacy. The Hebrew word for "refuse" (מָאֵן, ma'en) implies a stubbornness or unwillingness to comply. This reflects Pharaoh's hardened heart, a recurring theme in Exodus, symbolizing resistance to divine command. The phrase "let My people go" underscores God's claim over Israel, emphasizing their identity as His chosen people, destined for freedom and worship.

I will send swarms of flies
The Hebrew term for "swarms" (עָרוֹב, 'arov) is often interpreted as a mixture of insects, possibly including flies, gnats, or other pests. This plague represents a direct assault on the Egyptian way of life, disrupting daily activities and religious practices. In the ancient world, flies were not only a nuisance but also carriers of disease, symbolizing chaos and divine judgment. The sending of these swarms illustrates God's control over nature and His ability to use creation to fulfill His purposes.

on you and your officials and your people
This phrase indicates the comprehensive nature of the plague, affecting all levels of Egyptian society. The inclusion of "officials" (עֲבָדֶיךָ, avadekha) highlights the political implications of the plagues, as Pharaoh's advisors and administrators are also subject to God's judgment. This serves as a reminder that no one is beyond the reach of divine justice, and that leadership carries responsibility for the welfare of the people.

and into your houses
The invasion of homes signifies a personal and intimate disruption, as the sanctity of private space is violated. In ancient Egypt, homes were places of refuge and security, and this plague shatters that sense of safety. The presence of flies in the houses symbolizes the pervasive nature of sin and the inescapable reach of God's judgment when His commands are ignored.

The houses of the Egyptians will be full of flies
This statement emphasizes the severity and totality of the plague. The word "full" (מָלֵא, male) conveys a sense of overwhelming abundance, leaving no room for comfort or relief. The Egyptians' homes, once places of order and control, become chaotic and uninhabitable, reflecting the disorder that results from defying God's will.

and even the ground where they stand
The phrase "even the ground" (וְגַם הָאֲדָמָה, vegam ha'adamah) suggests that the plague extends beyond the immediate environment to affect the very foundation of Egyptian life. The ground, often associated with stability and sustenance, becomes a source of discomfort and distress. This serves as a powerful metaphor for the consequences of sin, illustrating how rebellion against God can undermine the very ground upon which society stands.

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,
