Chasidut על שמות 23:5

You must not see the donkey of your brother (Deut. 22:4) crouching under his burden (Ex. 23:5) etc - that a person that busies themselves with the issues and businesses of this world, behold, the world is like a burden for them, and they crouch under its burden, and the text says "you must not ignore": this is a warning for the tzadik to pray for that person. And this is easy to understand.
