Deuteronomy 32:3-6

3 Because I will publish the name of the LORD: ascribe you greatness to our God.

4 He is the Rock, his work is perfect: for all his ways are judgment: a God of truth and without iniquity, just and right is he.

5 They have corrupted themselves, their spot is not the spot of his children: they are a perverse and crooked generation.

6 Do you thus requite the LORD, O foolish people and unwise? is not he your father that has bought you? has he not made you, and established you?
