Philemon 1:15

“For perhaps he therefore departed for a season, &c.] 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 (<022106>Exodus 21:6) or to all eternity, since…”

“perhaps--speaking in human fashion, yet as one believing that God's Providence probably (for we cannot dogmatically define the hidden purposes of God in providence) overruled the past evil to ultimately greater good to him. This thought would soften Philemon's indignation at Onesimus' past offense. So Joseph in Gen 45:5. departed--literally, "was parted from thee"; a softening term for "ran away," to mitigate Philemon's wrath. receive him--Greek, "have him for thyself in full possession" (see on Phi 4:18). The same Greek as in Mat 6:2. for ever--in this life and in that to come (compare Exo 21:6). Onesimus' time of absence, however long, was but a short "hour" (so Greek) compared with the…”

“For perhaps he therefore departed for a season - Perhaps on this account, or for this reason - διὰ τοῦτο dia touto - he left you for a little time. Greek, “for an hour” - πρὸς ὥραν pros hōran. The meaning is, that it was possible that this was permitted in the Providence of God in order that Onesimus might be brought under the influence of the gospel, and be far more serviceable to Philemon as a Christian, than he could have been in his former relation to him. What appeared to Philemon, therefore, to be a calamity, and what seemed to him to be wrong on the part of Onesimus, might have been permitted to occur in order that he might receive a higher benefit. Such things are not uncommon…”

“God might permit him to be separated (a soft word) for a season, that thou mightest have him for ever - Both on earth and in heaven. Philemon 1:16”

“1:15 you lost Onesimus (literally he went away): This might be a euphemism for running away, in order not to mention Onesimus’s offense directly. • so that you could have him back forever: It is implied that God providentially arranged events to lead to Onesimus’s salvation.”
