'Blot' in the Bible

desist from Me, and I destroy them, and blot out their name from under the heavens, and I make thee become a nation more mighty and numerous than it.

And it hath been, in Jehovah thy God's giving rest to thee, from all thine enemies round about, in the land which Jehovah thy God is giving to thee -- an inheritance to possess it -- thou dost blot out the remembrance of Amalek from under the heavens -- thou dost not forget.
