Deuteronomy 32:5-7

Amplified Bible

⁵ 
“They (Israel) have acted corruptly toward Him.
They are not His children, because of their [moral] defect;
But are a perverse and crooked generation.
⁶ 
“Do you thus repay the Lord,
O foolish and unwise people?
Is not He your Father who has acquired you [as His own]?
He has made you and established you [as a nation].
⁷ 
“Remember the days of old,
Consider the years of many generations.
Ask your father, and he will inform you,
Your elders, and they will tell you.
