Error correction ongoing

I am going to present a psalm to our Bible study - it is a challenge to make it devotional and participatory when I tend to dump so much into one psalm. We are doing Psalm 19 - and I have corrected a few glaring errors in my translation. I did say 6 years for this exercise - not 2, so I am not too surprised that I have refinement to do especially including any posts that are internally linked on the right hand sidebar. This blog is not meant to be transient comments but a means to understanding the question: how did the New Testament authors use their psalter and why?
