Ezra 9:10-12

10Now, our God, what can we say in light of this? For we have abandoned the commands

11you gave through your servants the prophets, saying, “The land you are entering to possess is an impure land. The surrounding peoples have filled it from end to end with their uncleanness by their impurity and detestable practices.

12So do not give your daughters to their sons in marriage or take their daughters for your sons. Never pursue their welfare 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.”
