John Gill Commentary Acts 15:29

"that ye abstain from things sacrificed to idols, and from blood, and from things strangled, and from fornication; from which if ye keep yourselves, it shall be well with you. Fare ye well." — Acts 15:29 (ASV)

That you abstain from meats offered to idols
Which explains what is meant by pollutions of idols, (Acts 15:20)

and from blood, and from things strangled, and from fornication
(See Gill on Acts 15:20)

In Beza's most ancient copy, and in three other manuscripts, and in the Complutensian edition, it follows, "and whatsoever you would not have done to yourselves, that do you not to another"; in like manner the Ethiopic version also reads, as in (Acts 15:20) "from which if you keep yourselves you shall do well"; it will be doing a good thing, and make for the peace of the churches;

in Beza's most ancient copy it is added, "born", or "moved by the Holy Ghost": being influenced and assisted by him in this, and every good work:

fare you well ;
the Syriac version adds, "in our Lord".
