"when you left Egypt": the time of your redemption, and all was stopped because of her, whereby we are apprised that all of that time when the standards of the tribes traveled, they did so only when Miriam preceded them, viz. (Michah 6:4) "And I sent before you Moses, Aaron, and Miriam."
(Devarim 24:10) "When your neighbor is indebted to you, any kind of debt, do not enter his house to claim his pledge." "When your neighbor is indebted to you": This tells me only of a loan. Whence do I derive (the same for) a laborer's wages and store-credit? From "any kind of debt."
