Acts 15:20, 25, 29

but that we write unto them, that they abstain from pollutions of idols, and from fornication, and from things strangled, and from blood.

it seemed good unto us, being assembled with one accord, to send chosen men unto you with our beloved Barnabas and Paul

that ye abstain from meats offered to idols, and from blood, and from things strangled, and from fornication: from which if ye keep yourselves, ye shall do well. Fare ye well.
