Then, from a link on textweek.com, I came across Psalm 91 set by Dales Schoening to the tune of Finlandia. I can't get that link to work any more, but perhaps this one will help the more knowledgable of you)
Yes, the Psalm can be misused, but we do rely on God to rescue us.
When they call to me, I will answer them;Listen to Sons of Korah sing this psalm.
I will be with them in trouble,
I will rescue them and honor them.
With long life I will satisfy them,
and show them my salvation (15-16).
