Ezra 9:10-12

10"And now, O our God, what shall we say after this? For we have forsaken your commandments,

11which you commanded by your servants the prophets, saying, 'The land that you are entering, to take possession of it, is a land impure with the impurity of the peoples of the lands, with their abominations that have filled it from end to end with their uncleanness.

12Therefore do not give your daughters to their sons, neither take their daughters for your sons, and never seek their peace or prosperity, that you may be strong and eat the good of the land and leave it for an inheritance to your children forever.'
