Ezra 9:11-12

ASV_Strongs(i)
  11 H6680 which you have commanded H3027 by H5650 your servants H5030 the prophets, H559 saying, H776 The land, H935 unto which you go H3423 to possess H5079 it, is an unclean H776 land H5079 through the uncleanness H5971 of the peoples H776 of the lands, H8441 through their abominations, H4390 which have filled H6310 it from one end H6310 to another H2932 with their filthiness:
  12 H5414 now therefore give H1323 not your daughters H1121 unto their sons, H5375 neither take H1323 their daughters H1121 unto your sons, H1875 nor seek H7965 their peace H2896 or their prosperity H5704 for H5769 ever; H2388 that you may be strong, H398 and eat H2898 the good H776 of the land, H3423 and leave it for an inheritance H1121 to your sons H5769 for ever.
