'Blot' in the Bible

The Lord then said to Moses, “Write this down on a scroll as a reminder and recite it to Joshua: I will completely blot out the memory of Amalek under heaven.”

When My Angel goes before you and brings you to [the land of] the Amorite, the Hittite, the Perizzite, the Canaanite, the Hivite, and the Jebusite, I will reject them and completely destroy them.

Yet now, if thou wilt forgive their sin ; and if not, blot me, I pray thee, out of thy book which thou hast written.

And the LORD said unto Moses, Whosoever hath sinned against me, him will I blot out of my book.
