G4724–στέλλω–stellō

And so that no man might be able to say anything against us in the business of this giving which has been put into our hands:

στελλόμενοι stellomenoi “avoiding”

Now we give you orders, brothers, in the name of our Lord Jesus Christ, to keep away from all those whose behaviour is not well ordered and in harmony with the teaching which they had from us.

στέλλεσθαι stellesthai “are to withdraw”
