ייִדישער מחשבֿה אויף תהילים 146:3

If a slave has more than one master, and each one has the power to help him, it is not possible for him to put his trust in only one of them, since he hopes to benefit from each master. And if one master can benefit him more than the others, he should trust proportionally more in him, even though he also trusts in the others. And if only one of the masters can benefit him or harm him, certainly he should put his trust only on that master, since he does not hope for benefit from the other masters. Similarly, when a human being will realize that no created being can benefit him or harm him without the permission of the Creator, he will stop being afraid of them or of hoping for anything from them, and he will place his trust in the Creator alone, as written "Put not your trust in princes, nor in mortal man who has no help" (Tehilim 146:3).
