G1128–γυμνάζω–gumnazō

But have nothing to do with unclean and foolish stories. Give yourself training in religion:

γύμναζε gumnaze “do train”

But solid food is for men of full growth, even for those whose senses are trained by use to see what is good and what is evil.

γεγυμνασμένα gegumnasmena “trained”

At the time all punishment seems to be pain and not joy: but after, those who have been trained by it get from it the peace-giving fruit of righteousness.

γεγυμνασμένοις gegumnasmenois “trained”

Having eyes full of evil desire, never having enough of sin; turning feeble souls out of the true way; they are children of cursing, whose hearts are well used to bitter envy;

γεγυμνασμένην gegumnasmenēn “exercised”
