The poor use entreaties, but the rich answer roughly.

Matthew Henry Presbyterian @wholebiblehenry

Note, 1. Poverty, though many inconveniences to the body attend it, has often a good effect upon the spirit, for it makes men humble and submissive, and mortifies their pride. It teaches them to use entreaties. When necessity forces men to beg it tells them they must not prescribe or demand, but take what is given them and be thankful.

John Gill Reformed Baptist @doctorgill

The poor useth entreaties,.... Or "supplications" (a); he is an humble supplicant to others for favours he asks in a submissive and lowly manner; he does not demand anything, nor prescribe what shall be done for him, but modestly tells his case, and submits it; so such who are poor in spirit are humble supplicants at the throne of grace; but the rich answereth roughly...

Jamieson-Fausset-Brown Reformed @jfbcommentary

the rich . . . roughly--He is tolerated because rich, implying that the estimate of men by wealth is wrong.
