Thus were they defiled with their works, And played the harlot in their doings.

So they became unclean through their works, going after their evil desires.

Και εμολυνθησαν με τα εργα αυτων, και επορνευσαν με τας πραξεις αυτων.

Thus were they defiled with their own works, and went a whoring with their own inventions.

Thus were they defiled with their works, and prostituted themselves in their deeds.
