Romans 16:2 - Matthew Poole's English Annotations on the Holy Bible

Receive her in the Lord; i.e. in the Lord's name, or for the Lord's sake: see Matthew 18:5. Or else it is as if he had said: Receive her Christianly. As becometh saints; as it is fit that saints should be rcceived, or as it is fit for them, who profess themselves to be saints, to receive one another. That ye assist her in whatsoever business she hath need of you; that you stand by her, and afford her your counsel, or any other assistance. She might have some business in the emperor's court, by reason of fraud, oppression, or some unjust vexations; and there might be those amongst them that could stand her in some stead. There were Christians of Caesar's household, Philippians 4:22. For she hath been a succourer of many, and of myself also: the word signifieth a patroness. She had been hospitable to many, and in particular, to the apostle himself. This showeth she was a woman of some account: it was but equal that the saints at Rome should assist her, who had been assistant unto so many others.
