Ezekiel 9:6

They were told not to harm the grass of the earth or any plant or tree, but only those who did not have the seal of God on their foreheads.

When the LORD passes through to strike down the Egyptians, He will see the blood on the top and sides of the doorframe and will pass over that doorway; so He will not allow the destroyer to enter your houses and strike you down.

For behold, I am beginning to bring disaster on the city that bears My Name, so how could you possibly go unpunished? You will not go unpunished, for I am calling down a sword upon all the inhabitants of the earth, declares the LORD of Hosts.’

Nevertheless, God’s firm foundation stands, bearing this seal: “The Lord knows those who are His,” and, “Everyone who calls on the name of the Lord must turn away from iniquity.”

“Do not harm the land or sea or trees until we have sealed the foreheads of the servants of our God.”

That servant who knows his master’s will but does not get ready or follow his instructions will be beaten with many blows.

So He brought up against them the king of the Chaldeans, who put their young men to the sword in the sanctuary, sparing neither young men nor young women, neither elderly nor infirm. God gave them all into the hand of Nebuchadnezzar,

Now go and attack the Amalekites and devote to destruction all that belongs to them. Do not spare them, but put to death men and women, children and infants, oxen and sheep, camels and donkeys.’”

At that time we captured all his cities and devoted to destruction the people of every city, including women and children. We left no survivors.

We devoted them to destruction, as we had done to Sihon king of Heshbon, utterly destroying the men, women, and children of every city.
