"my tongue shall tell"

I prayed these lines at the end of Psalm 35 this morning:

Let those who desire my vindication
shout for joy and be glad,
and say evermore, "Great is the LORD,
who delights in the welfare of his servant!"
Then my tongue shall tell of your righteousness
and of your praise all the day long.

And I was immediately taken back over a year, to a snowy morning last February. Now I sit only a few hundred yards away. But we've come so far.
