Psalm 105:29

Praise To Yahweh For His Work On Behalf Of Israel

²⁸
He sent [thick, oppressive] darkness and made the land dark;
And Moses and Aaron did not rebel against His words.
²⁹ 
He turned Egypt’s waters into blood
And caused their fish to die.
³⁰
Their land swarmed with frogs,
Even in the chambers of their kings.

And their streams, so that they could not drink.

Isaiah 50:2

“Why, when I came, was there no man [to greet Me]?
When I called, why was there no one to answer?
Is My hand really so short that it cannot redeem [My servants]?
Or have I no power to rescue?
Listen carefully, with My rebuke I dry up the sea,
I make the rivers into a desert;
Their fish stink because there is no water
And die of thirst.

Ezekiel 29:4-5

“I will put hooks in your jaws
And [I will] make the fish of your rivers stick to your scales.
And I will pull you up from the midst of your rivers,
And all the fish of your rivers will stick to your scales.
