Ezra 9:10-12

10“Now, our God, what shall we say after this? For we have forsaken Your commandments,

11which You have commanded by Your servants the prophets, saying, ‘The land which you are entering to possess is an unclean land with the uncleanness of the peoples of the lands, with their abominations which have filled it from end to end and 1with their impurity.

12So now do not 2give your daughters to their sons nor take their daughters to your sons, and 3never seek their peace or their prosperity, that you may be strong and eat the good things of the land and 4leave it as an inheritance to your sons forever.’
