For perhaps he therefore departed for a season
The apostle in this clause seems to soften this business of Onesimus in running away from his master; he calls it not a running away, but a departure, an absence from him, and that but for a little while; and suggests that the hand of God might be in it; that there was an overruling providence that attended it, such as was in Joseph's going down into Egypt; and that this separation of Onesimus from his master, for a short time, was in order that they should come together again, and never part more, as follows:
that thou shouldest receive him for ever;
or during life, referring to the law in ( Exodus 21:6 ) or to all eternity, since they were in the same spiritual relation, partakers of the same grace, and had a right to the same heavenly inheritance, and should be together with Christ for evermore.
