tsadiq refers to the "righteous"
in the sense of being and acting rightly and justly. God is both righteous and
the support of the righteous. The word is at home in both legal and 'religious'
contexts. In Amos the "righteous" (tsadiq)
is used in parallel with 'ebyon
the needy or lower class
in both 2:6 and 5:12.
