'Blot' in the Bible

Let Me alone, so that I may destroy them and wipe out their name from under heaven; and I will make of you a nation mightier and greater than they.’

Therefore when the Lord your God has given you rest from all your surrounding enemies, in the land which the Lord your God gives you as an inheritance to possess, you shall wipe out the memory of Amalek from under heaven; you must not forget.

the Lord will not be willing to forgive him, but then the anger of the Lord and His jealousy will burn against that man, and every curse which is written in this book will rest on him; the Lord will blot out his name from under heaven.
