'Marry' in the Bible

So I entered a complaint with them. I called down a curse on them, and I struck some of the men and pulled out their hair. I had them swear by God saying, "You will not marry off your daughters to their sons, and you will not take any of their daughters as wives for your sons or for yourselves!

Should we listen to you and do all of this terrible evil by transgressing against our God to marry foreign wives?"
