'Oppressing' in the Bible

For I am the least [worthy] of the apostles, and not fit to be called an apostle, because I [at one time] fiercely oppressed and violently persecuted the church of God.

For we do not want you to be uninformed, brothers and sisters, about our trouble in [the west coast province of] Asia [Minor], how we were utterly weighed down, beyond our strength, so that we despaired even of life [itself].

But you have dishonored the poor! Are not the rich oppressing you and dragging you into the courts?
