Golden opportunity[1]
אלה הדברים אשר דבר משה אל-כל-ישראל בעבר הירדן בערבה מול סוף בין-פארן ובין-תפל ולבן וחצרת ודי זהב
These are the words that Moshe told all of Israel, across the Jordan River, in Aravah, across from the Reed Sea, between Paran and Tofel, and Lavan, and Chatzeiros, and Di Zahav[2]
In the beginning of Sefer Devarim we are told that Moshe spoke to the entire Jewish people. The Torah is extremely precise with the location of this speech. Rashi explains[3] that in fact, the Torah is not telling us geographical information. Really, Moshe was rebuking the people. The places that the Torah is telling us are allusions to prior sins that the Jews committed. Focusing on the last one, Di Zahav, we are told that it is a reference to the sin of the Golden Calf. The hint is that the Jews had so much gold from the Egyptians, that they yelled out “Dai”, meaning “Enough!”. They didn’t know what to do with it, so they ended up making a Golden Calf as an idol[4].
