Exodus 23:3-6

3nor shall you favor or be partial to a poor man in his dispute [simply because he is poor].

4“If you meet your enemy’s ox or his donkey wandering off, you must bring it back to him.

5If you see the donkey of one who hates you lying helpless under its load, you shall not leave the man to deal with it [alone]; you must help him release the animal [from its burden].

6“You shall not pervert (bend) the justice due to your poor in his dispute.
