SEV Biblia, Chapter 7:3
Y no emparentarás con ellos; no darás tu hija a su hijo, ni tomarás a su hija para tu hijo.
Clarke's Bible Commentary - Deuteronomy 7:3
Verse 3. Neither shalt thou make marriages, &c.] The heart being naturally inclined to evil, there is more likelihood that the idolatrous wife should draw aside the believing husband, than that the believing husband should be able to bring over his idolatrous wife to the true faith.
John Gill's Bible Commentary
Ver. 3. Neither shalt thou make marriages with them , etc.] Unless they became proselytes, as Rahab, who was married by Salmon, and so those of other nations, as Ruth the Moabitess, and so any captive taken in war; otherwise it was not lawful, bad consequences have followed upon it, which it is the design of this law to prevent; that is, being snared and drawn aside into idolatry, which was the case of Solomon: thy daughter thou shalt not give unto his son, nor his daughter shalt thou take unto thy son ; for, according to the Targum of Jonathan, whosoever marries with them, it is as if he married with their idols: and this law, according to the Jewish writers f75 , is binding with respect to other nations besides the seven; and whosoever marries any Heathen, of whatsoever nation, is to be beaten.
Matthew Henry Commentary
Verses 1-11 - Here is a strict caution against all friendship and fellowship with idols and idolaters. Those who are in communion with God, must have n communication with the unfruitful works of darkness. Limiting the orders to destroy, to the nations here mentioned, plainly shows tha after ages were not to draw this into a precedent. A prope understanding of the evil of sin, and of the mystery of a crucifie Saviour, will enable us to perceive the justice of God in all his punishments, temporal and eternal. We must deal decidedly with ou lusts that war against our souls; let us not show them any mercy, but mortify, and crucify, and utterly destroy them. Thousands in the worl that now is, have been undone by ungodly marriages; for there is mor likelihood that the good will be perverted, than that the bad will be converted. Those who, in choosing yoke-fellows, keep not within the bounds of a profession of religion, cannot promise themselves help meet for them.
