Deuteronomy 32:3-5

Young's Literal Translation

³ For the Name of Jehovah I proclaim, Ascribe ye greatness to our God!

⁴ The Rock! -- perfect [is] His work, For all His ways [are] just; God of stedfastness, and without iniquity: Righteous and upright [is] He.

⁵ It hath done corruptly to Him; Their blemish is not His sons', A generation perverse and crooked!
