Ac 21:25 But as touching the Gentiles that have believed, we wrote, giving judgment that they should keep themselves from things sacrificed to idols, and from blood, and from what is strangled, and from fornication (porneia).
Re 19:2 for true and righteous are his judgments; for he hath judged the great harlot, her that corrupted the earth with her fornication (porneia), and he hath avenged the blood of his servants at her hand.

The Greek word porneia translated fornication in both of the above verses point to the 2nd definition of porneia since they speak of a corrupt form of worship.
