Not for thine own righteousness、 nor for the uprightness of thine own heart art thou going in to possess their land,—but for the lawlessness of these nations is Yahweh thy God driving them out from before thee, and that he may establish the word which Yahweh sware unto thy fathers, unto Abraham、 unto Isaac、 and unto Jacob. So then, thou must consider that not for thine own righteousness is Yahweh thy God giving unto thee this good land、 to possess it,—for a stiff-necked people thou art.
Deuteronomy 9:5–6
