'Marriage' in the Bible

So do not give your daughters to their sons in marriage or take their daughters for your sons. Never seek their peace or prosperity, so that you will be strong, eat the good things of the land, and leave it as an inheritance to your sons forever.”

do we turn back to break Thy commands, and to join ourselves in marriage with the people of these abominations? art not Thou angry against us -- even to consumption -- till there is no remnant and escaped part?
