Their only recourse

If you lend money – Mishpatim

"Kol Almana V'Yason Lo Si'anun... "Ki Im Tza'ok Yitzak Eilai Shamoa Eshma Tzaakosoi", do not pain a widow or orphan... if they will scream to me I will answer (Mishpatim 22:22-23). Do widows and orphans get preferential treatment. If yes, how can we get the same treatment?

Rav Itzele Volozhin says that every person in the world who experiences pain and suffering, takes their problems straight to their patron. This could be a child to father or a wife to her husband. In that case Hashem stands on the side and let's justice take its course, as he was not called in to the picture.

A widow or orphan has worldly address to file his grievances. Their only recourse is to lift their eyes to their father in Shamayim and beg Him for help. Hashem the Av HaRachaman of course takes care of his dear suffering children.

You don't need to be an orphan or widow to get Hashem's attention. All you need to do is to take your problems to him as you first and only real choice. Then you too can be answered and your pleas will not be ignore. "Ki Im Tza'ok Yitzak Eilai", if you scream to Me. "Shamoa Eshma Tzaakosoi", I will listen to your cries.
