Ezra 9:10-12

10And now, what shall we say, our 1God, after this? for we have forsaken thy commandments,

11which thou hast commanded by thy servants the prophets, saying, The land, unto which ye go to possess [it], is an unclean land through the filthiness of the peoples of the lands, through their abominations with which they have filled it from one end to another through their uncleanness.

12Now therefore give not your daughters to their sons, neither take their daughters to your sons, nor seek their peace or their prosperity for ever; that ye may be strong, and eat the good of the land, and leave it for an inheritance to your children for ever.
