Deuteronomy 9:5-6

ASV_Strongs(i)
  5 H6666 Not for thy righteousness, H3476 or for the uprightness H3824 of thy heart, H935 dost thou go H3423 in to possess H776 their land; H7564 but for the wickedness H1471 of these nations H3068 Jehovah H430 thy God H3423 doth drive them out H6440 from before H6965 thee, and that he may establish H1697 the word H3068 which Jehovah H7650 sware H1 unto thy fathers, H85 to Abraham, H3327 to Isaac, H3290 and to Jacob.
  6 H3045 Know H3068 therefore, that Jehovah H430 thy God H5414 giveth H2896 thee not this good H776 land H3423 to possess H6666 it for thy righteousness; H6203 for thou art a stiffnecked H5971 people.
