Now therefore give not your daughters unto their sons, nor take their daughters unto your sons,.... That is, in marriage, see Deuteronomy 7:3, where the prohibition is expressed in the same language:
nor seek their peace or their wealth for ever; that is, as long as they continue in their idolatries and impurities, see Deuteronomy 23:6,
that ye may be strong, and eat the good of the land, and leave it for an inheritance to your children for ever; that they might be strengthened and established in the land into which they were brought, and enjoy all the good things it produced, and leave their children in the possession of it, to hold at least until the Messiah came, see Isaiah 1:19.
Strong - Although you may fancy making leagues and marriages with them, as the only way to establish you, yet I assure you, it will weaken and ruin you, and the contrary course will make you strong.
