New King James Version
16 I will go in the strength of the Lord God;
I will make mention of Your righteousness, of Yours only.
17 O God, You have taught me from my (A)youth;
And to this day I declare Your wondrous works.
18 Now also (B)when I am old and grayheaded,
O God, do not forsake me,
Until I declare Your strength to this generation,
Your power to everyone who is to come.
