Anak in the Bible

And they were known as giants, like the sons of Anak, but the Moabites called them Emim.

a great and plentiful people, and tall, like the sons of Anak, but Jehovah destroyed them before them. And they expelled them and lived in their place,

A people great and tall, the children of the Anakims, whom thou knowest, and of whom thou hast heard say, Who can stand before the children of Anak!
