'Blot' in the Bible

So the Lord said, “I will destroy (annihilate) mankind whom I have created from the surface of the earth—not only man, but the animals and the crawling things and the birds of the air—because it [deeply] grieves Me [to see mankind’s sin] and I regret that I have made them.”

For in seven days I am going to cause it to rain on the earth for forty days and forty nights; and I will destroy (blot out, wipe away) every living thing that I have made from the surface of the earth.”
