chained_bear commented on the word mackerel-snapper I get the fish-eater thing, but I don't know why non-Catholics wouldn't want mackerel--evidenced by the use of the term in a disparaging phrase. (Or wouldn't want snapper, for that matter.)
Psalm 1 is the first of the Psalms in the Hebrew Bible. Like many of the psalms, it contrasts the  righteous  person (tzadik ×¦×××§) to the wicked or ungodly (rasha` ×¨×©×¢) or the  sinner  (chatta' ×××).
Psalm one is a wisdom Psalm. There are praise Psalms, lament Psalms, and enthronement Psalms and all contain wisdom, of course, but as an introduction and door to the rest of the Psalms, this Psalm declares in just a few words some of the most basic but profound truths and propositions of the Bible.his first Psalm stands as a kind of introduction to the rest of the Psalms. Its subject matter is very general and basic, but it touches on two subjects that continually occur throughout the Psalms. It declares the blessedness of the righteous and the misery and future of the wicked.
