Never Will I Leave You, Never Will I Forsake You

Let your conversation be without covetousness; and be content with such things as ye have: for he hath said, I will never leave thee, nor forsake thee.
- Hebrews 13:5 (KJV)

Which is very similar to:

Be strong and of a good courage, fear not, nor be afraid of them: for the Lord thy God, he it is that doth go with thee; he will not fail thee, nor forsake thee.
- Deuteronomy 31:6 (KJV)
