” Our tradition teaches that the oppressed, the poor, the hungry, the downtrodden will inherit the earth.”
Better get that geirus checked, buddy. That may be what Matthew told you but the passuk in tehillim lehavdil should not be read with christian colored glasses.
Inherit the land means meeting moshiach (Rashi in Sanhedrin 98)
The humble refers to tzaddikim, as is explicit in passuk 29. The other passukim (9, 11, 18, 22, etc) use adjectives for tzaddikim instead of the word itself. Nowhere in the torah do we degrade the rich or unoppressed for having advantages in life, nor do we find preferrential treatment for any characteristic other than righteousness.
