'Sexual Immorality' in the Bible

but to write [urging] them to avoid [eating] what is contaminated by [its association with] idol worship, from sexual immorality, from [eating] strangled animals and from [drinking] blood.

Avoid [eating] things sacrificed to idols; avoid [drinking] blood; avoid [eating] things [that were] strangled [to death] and avoid sexual immorality. If you avoid [all] these things, you will be doing well. Goodbye."

But concerning Gentile believers, we wrote [to them] our decision, that they should avoid [eating] things sacrificed to idols, from [drinking] blood, from [eating] what is strangled and from sexual immorality."
