5The Egyptians ashall know that I am the Lord, when I stretch out my hand against Egypt and bring out the people of Israel from among them.”

Exodus 9:14

14For this time I will send all my plagues on you yourself,
Hebrew  on your heart
and on your servants and your people, so cthat you may know that there is none like me in all the earth.

Psalms 78:43-51

43 dwhen he performed his esigns in Egypt
and his fmarvels in gthe fields of Zoan.
44He hturned their rivers to blood,
so that they could not drink of their streams.
45He sent among them swarms of iflies, which devoured them,
and jfrogs, which destroyed them.
46He gave their crops to kthe destroying locust
and the fruit of their labor to the locust.
47He destroyed their vines with lhail
and their sycamores with frost.
48He gave over their mcattle to the hail
and their flocks to thunderbolts.
49He let loose on them his burning anger,
wrath, indignation, and distress,
a company of ndestroying angels.
50He made a path for his anger;
he did not spare them from death,
but gave their lives over to the plague.
51He struck down every ofirstborn in Egypt,
the firstfruits of their strength in the tents of pHam.
