Let the favor of the Lord our God be upon us,This is an excellent way to end this Psalm.
and establish the work of our hands upon us;
yes, establish the work of our hands!
"Favor" could also be translated as "beauty" or "pleasantness". This is what we desire. We want those beautiful qualities of the Lord to be upon us. We desire for our own character to match that beautiful character of God. And we also desire to have what we do be firm and solidified, but only if what we do is matching His beauty.
