Psalm 71:15-18

Young's Literal Translation

¹⁵ My mouth recounteth Thy righteousness, All the day Thy salvation, For I have not known the numbers.

¹⁶ I come in the might of the Lord Jehovah, I mention Thy righteousness -- Thine only.

¹⁷ God, Thou hast taught me from my youth, And hitherto I declare Thy wonders.

¹⁸ And also unto old age and grey hairs, O God, forsake me not, Till I declare Thy strength to a generation, To every one that cometh Thy might.
