Psalms 71:15-18

ASV(i) 15 My mouth shall tell of thy righteousness,
[And] of thy salvation all the day;
For I know not the numbers [thereof]. 16 I will come with the mighty acts of the Lord Jehovah:
I will make mention of thy righteousness, even of thine only. 17 O God, thou hast taught me from my youth;
And hitherto have I declared thy wondrous works. 18 Yea, even when I am old and grayheaded, O God, forsake me not,
Until I have declared thy strength unto [the next] generation,
Thy might to every one that is to come.
