'Blot' in the Bible

And Jehovah said to Moses, Write this for a memorial in the book, and rehearse it in the ears of Joshua, that I will utterly blot out the remembrance of Amalek from under the heavens.

And now, if thou wilt forgive their sin ... but if not, blot me, I pray thee, out of thy book that thou hast written.

And Jehovah said to Moses, Whoever hath sinned against me, him will I blot out of my book.
