Were Abraham's and Lot's guests the same?
Genesis 18 describes "אנשים [=men]" who came to visit Abraham. Chapter 19 starts "And the two מלאכים [=messengers, or angels] arrived at Sodom…" and proceeds to call them, too, "אנשים".
Rashi and many other commentaries to 19:1 take for granted that these were the same men as in chapter 18, which indeed seems the obvious reference of the definite article "the two מלאכים".
I wonder whether any classical commentaries differ and how they explain the definite article. Or, on the contrary, I wonder whether there's any support from the text itself, besides that definite article, for the claim that the chapter-19 people (or beings) were the same as the chapter-18 ones.
