'Blot' in the Bible

let me alone, that I may destroy them, and blot out their name from under the sky; and I will make of you a nation mightier and greater than they."

Therefore it shall be, when Yahweh your God has given you rest from all your enemies all around, in the land which Yahweh your God gives you for an inheritance to possess it, that you shall blot out the memory of Amalek from under the sky; you shall not forget.

Yahweh will not pardon him, but then the anger of Yahweh and his jealousy will smoke against that man, and all the curse that is written in this book shall lie on him, and Yahweh will blot out his name from under the sky.
