1. ptochos = destitute, and in want: always rendered "poor" : except in Luke 16:20, 22 (beggar); Gal. 4:9 (beggarly); Jas. 2:2 (poor man).
2. penes = poor, as opposed to rich. Occurs only in 2Cor. 9:9.
3. praiis = meek, as distinguished from passionate. Occ. only in Matt. 5:5; 21:5; 1Pet. 3:4.
These words are used in the Septuagint interchangeably for the same
Hebrew word; but the contexts show that they are all used for the same
class, viz., the fellahin, or poor of an oppressed country, living
quite lives under tyrannical and oppressive rulers; and suffering deprivation
from tax-gatherers and lawless neighbors.
