“Neither shalt thou make marriages with them; thy daughter thou shalt not give unto his son, nor his daughter shalt thou take unto thy son.”
King James Version (KJV)
7:1 Seven nations - There were ten in #Gen 15:19 |- 21. But this being some hundreds of years after, it is not strange if three of them were either destroyed by foreign or domestick wars, or by cohabitation and marriage united with, and swallowed up in the rest.
7:4 To serve other Gods - That is, there is manifest danger of apostacy and idolatry from such matches. Which reason doth both limit the law to such of these as are unconverted (otherwise Salmon married Rahab, #Matt 1:5|) and enlarge it to other idolatrous nations, as appears from #1Kin 11:2 Ezra 9:2 Neh 13:23|.
7:5 Their graves - Which idolaters planted about the temples and altars of their Gods. Hereby God designed to take away whatsoever might bring their idolatry to remembrance, or occasion the reviving of it.
