Leviticus 25:45ESV·traditional attribution

You may also buy from among the strangers who sojourn with you and their clans that are with you, who have been born in your land, and they may be your property.

Matthew Henry Presbyterian @wholebiblehenry

We have here the laws concerning servitude, designed to preserve the honour of the Jewish nation as a free people, and rescued by a divine power out of the house of bondage, into the glorious liberty of God's sons, his first-born. Now the law is, I. That a native Israelite should never be made a bondman for perpetuity.

John Gill Reformed Baptist @doctorgill

Moreover, of the children of the strangers, that do sojourn among you,.... The uncircumcised sojourners as they are called in the Targums of Onkelos and Jonathan, proselytes of the gate, such of the nations round about who came and sojourned among them, being subject to the precepts given to the sons of Noah respecting idolatry, &c.

Geneva Bible Notes Reformed @genevanotes

Moreover of the children of the strangers that do sojourn among you, of them shall ye buy, and of their families that [are] with you, which they begat in your land: and they shall be your possession. (t) For they shall not be bought out at the Jubile.
