G1183–δεκατόω–dekatoō

But this man, who was not of their family, took the tenth from Abraham, and gave a blessing to him to whom God had given his undertaking.

δεδεκάτωκεν dedekatōken “he has collected a tenth”

And we may say that in Abraham, even Levi, who has a right to take the tenth part, gave it;

δεδεκάτωται. dedekatōtai “has paid the tithe.”
