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' ×××).
Psalmâs role in the Bible. Psalms is the second book of poetry in the Bible. While the poetic books of Job, Ecclesiastes, and Song of Solomon read as whole pieces, Psalms is a collection of 150 small units in one bookâsomewhat like todayâs hymnals.
