Rashi on Deuteronomy 32:6/רש"י על דברים ל״ב:ו׳

1הלה׳ תגמלו זאת DO YOU THUS REQUITE THE LORD? — This Is an expression of astonishment: Do you mean to grieve Him Who has the power to punish you, and Who has bestowed all these favours upon you?

2עם נבל A FOOLISH PEOPLE — i.e., a people that has forgotten all that has been done to them,

3ולא חכם AND NOT WISE to consider what will result from their actions, viz., that it is in His power to do them good or evil according to their actions (cf. Siphre).

4הלא הוא אביך קנך IS NOT HE THY FATHER קנך? The last word may mean: Who has acquired (קנה) thee, or, Who has placed thee (more lit., made thee nest, קנן) in a nest of rocks and in strong ground, or. Who has fitted you out (תקן) with everything that will benefit you.

5הוא עשך HE HATH MADE THEE a nation among the nations of the world,

6ויכננך AND HATH ESTABLISHED THEE afterwards on every kind of firm base and foundation (כן) (i.e. made you self-contained): out of your midst come your priests, out of your midst your Levites, and out of your midst your kings — a city in which is everything (Sifrei Devarim 309:7; Chullin 56b).
