Deuteronomy 32:5-7

5 They [Israel] have spoiled themselves. They are not sons to Him, and that is their blemish — a perverse and crooked generation!

6 Do you thus repay the Lord, you foolish and senseless people? Is not He your Father Who acquired you for His own, Who made and established you [as a nation]?

7 Remember the days of old; consider the years of many generations. Ask your father and he will show you, your elders, and they will tell you.
