Psalms 78:44
The miracles mentioned in this and the four subsequent verses, evidently shew the power of God over the elements of nature, which at that time were the objects of Egyptian worship.
Exodus 7:20-21
raised <07311> [he lifted.]
water ................... water <04325> [all the waters.]
As the Nile was held sacred by the Egyptians, as well as the animals it contained, to which they annually sacrificed a girl, or as others say, both a boy and girl, God might have designed this plague as a punishment for such idolatry and cruelty; and to shew them the baseness of those elements which they reverenced, and the insufficiency of the gods in which they trusted. All the punishments brought upon them bore a strict analogy to their crimes.
The first miracle of Christ turned water into wine, the first plague upon Egypt turned all their water into blood.
Isaiah 50:2
come <0935> [when I came.]
hand <03027> [Is my.]
power <03581> [have I.]
shout <01606> [at my.]
dry up <02717> [I dry.]
fish <01710> [their fish.]
Ezekiel 29:4-5
put <05414> [I will put.]
fish ...................... fish <01710> [the fish.]
leave <05203> [I will leave.]
open field <07704 06440> [open fields. Heb. face of the field. I have.]
Revelation 16:3
on <1519> [upon.]
it turned <1096> [it became.]
and ........... and every <2532 3956> [and every.]
