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' ×××).
The Psalms were mostly written by king David, Solomon wrote Proverbs Ecclesiastes and Song of Solomon. The rest of the prophetical books were written by the people who gave their names to the books e.g Daniel, Ezekiel. In the New Testament, Matthew, Mark, Luke and John were written by the men of those names; there are some variations on who people think wrote the Acts, but the most probably author seems to be Luke.
