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 127:3. Lo, children are a heritage of the Lord â They come not from the power of mere nature, but from Godâs blessing, even as an inheritance is not the fruit of a manâs own labour, but the gift of God.â5. All blessings are Godâs gift, but especially the blessing of a numerous family. In dilating upon its advantages the Psalmist passes away from the primary theme of the Psalm. Verse 3. - Lo, children are an heritage of the Lord.
