Psalms 71:15-18

15My mouth shall tell of Your righteousness And of Your [deeds of] salvation all day long, For their number is more than I know.

16I will come with the mighty acts of the Lord God [and in His strength]; I will make mention of Your righteousness, Yours alone.

17O God, You have taught me from my youth, And I still declare Your wondrous works and miraculous deeds.

18And even when I am old and gray-headed, O God, do not abandon me, Until I declare Your [mighty] strength to this generation, Your power to all who are to come.
