Isaiah 19:16-17
When God raises His hand, former powers become fearful and fragile.
16 In that day the Egyptians will be like women. They will tremble and fear because of the shaking of Yahweh of Armies’s hand, which he shakes over them.
17 The land of Judah will become a terror to Egypt. Everyone to whom mention is made of it will be afraid, because of the plans of Yahweh of Armies, which he determines against it.
When God raises his hand, former powers become fearful and fragile.
To portray Egypt’s fear in the face of the LORD’s raised hand and to show Judah becoming a source of dread because of divine purpose.
Egypt had long been a dominant regional power, yet Isaiah's prophecy portrays a future moment when the nation would fear the purposes of the LORD.
The Oracle Against Egypt, the Collapse of False Wisdom, and the Healing of the Nations
Isaiah 19 declares that the LORD judges Egypt’s idols, wisdom, economy, and false security, yet his purpose is so merciful and sovereign that Egypt will know him, worship him, be healed by him, and stand with Assyria and Israel as a blessing on the earth.
