Charles Ellicott Commentary Leviticus 25:48

"after that he is sold he may be redeemed: one of his brethren may redeem him;" — Leviticus 25:48 (ASV)

He may be redeemed again. —The law which applies to a heathen who sold himself to a Hebrew is reversed in this case. While the heathen cannot be redeemed, and is to remain a bondservant forever, the Israelite who sells himself to a heathen may be redeemed. Indeed, according to the interpretation which prevailed during the second Temple, this passage requires his relations and the congregation to redeem him as soon as possible. Hence the ancient Chaldee Version translates it, “his redemption must be effected immediately.”
