Joshua 23:11-13

ASV_Strongs(i)
  11 H3966 Take good H8104 heed H5315 therefore unto yourselves, H157 that ye love H3068 Jehovah H430 your God.
  12 H7725 Else if ye do at all H7725 go back, H1692 and cleave H3499 unto the remnant H1471 of these nations, H7604 even these that remain H2859 among you, and make marriages H935 with them, and go in unto them, and they to you;
  13 H3045 know H3045 for a certainty H3068 that Jehovah H430 your God H3254 will no more H1471 drive these nations H3423 from out H6440 of your sight; H6341 but they shall be a snare H4170 and a trap H7850 unto you, and a scourge H6654 in your sides, H6796 and thorns H5869 in your eyes, H6 until ye perish H2896 from off this good H127 land H3068 which Jehovah H430 your God H5414 hath given you.
