Comparison: Mormon 3:15 -> Romans 12:19

Mormon 3:15 (1830 edition page 524) Romans 12:19
Vengeance is mine, and I will repay; and because this people repented not after that I had delivered them, behold, they shall be cut off from the face of the earth. Dearly beloved, avenge not yourselves, but rather give place unto wrath: for it is written, Vengeance is mine; I will repay, saith the Lord.
