Deuteronomy 32:6-8

Amplified Bible

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.
⁸ 
“When the Most High gave the nations their inheritance,
When He separated the sons of man,
He set the boundaries of the peoples
According to the number of the sons of Israel.
