'Smite' in the Bible

So I will reach out My hand and strike Egypt with all My wonders which I shall do in the midst of it; and after that he will let you go.

Thus says the Lord, “By this you shall know and recognize and acknowledge that I am the Lord: look, with the staff in my hand I will strike the water in the Nile, and it shall be turned to blood.

However, if you refuse to let them go, hear this: I am going to strike your entire land with frogs.

For I [the Lord] will pass through the land of Egypt on this night, and will strike down all the firstborn in the land of Egypt, both man and animal; against all the gods of Egypt I will execute judgments [exhibiting their worthlessness]. I am the Lord.

The blood shall be a sign for you on [the doorposts of] the houses where you live; when I see the blood I shall pass over you, and no affliction shall happen to you to destroy you when I strike the land of Egypt.
