This work came about in a unique way and that is why it is so uniquely successful. Rabbi Aryeh Leib Lopiansky teaches Chumash to American students in Israel. They needed Torah thoughts to present to their Shabbos hosts, and he undertook to provide them two for each of the three Shabbos meals. Perfectionist that he is, he searched long and hard for the ones that would be best received. Deciding that he would choose selections based on halachic interpretation, he sifted through countless books, researched the sources, corrected errors, clarified ideas in short, he became a living source book for the sort of Torah comments that set a table with a lavish selection of Shabbos Delights.
