'Abstain from' in the Bible

And as to the matters now before you, I say unto you, Abstain from these men, and leave them to themselves: for if this design or this work be of men, it will come to nothing:

but that we write to them, that they abstain from pollutions of idol [sacrifices], and from whoredom, and from what is strangled, and from blood.

that ye abstain from eating whatever is sacrificed to idols, and from blood, and from what is strangled, and from whoredom: from which things carefully preserving yourselves, ye shall do well. Farewell.
