G3435–μολύνω–molunō

However, that knowledge isn't in all men. But some, with consciousness of the idol until now, eat as of a thing sacrificed to an idol, and their conscience, being weak, is defiled.

μολύνεται. molunetai “it is defiled.”

Nevertheless you have a few names in Sardis that did not defile their garments. They will walk with me in white, for they are worthy.

ἐμόλυναν emolunan “soiled”

These are those who were not defiled with women, for they are virgins. These are those who follow the Lamb wherever he goes. These were redeemed by Jesus from among men, the first fruits to God and to the Lamb.

ἐμολύνθησαν, emolunthēsan “was defiled,”
