It was Pesachhy, concerning Avraham, does it say (18:6), “Knead it and make rolls,” rather than matzos? It was Pesach, so it should have said “matzah rolls”! The answer is: Avraham ordered rich matzos to be made, [e.g. kneaded with oil and honey,] in honor of the guests.

לחם, “bread.” It is described as “bread” seeing that this is what the people tried to make it substitute for. Every kind of פת is called לחם, not only baked goods made from wheat or barley. We also encounter the term עוגות as describing bread, as in Genesis 18,6, and Numbers The term ממטיר is justified, as the Torah describes ingredients which rained down which would subsequently be converted into bread. Our benediction over bread is המוציא לחם מן הארץ, which also does not mean that G’d produces ready-made bread as emerging from the earth, but we thank Him for having the earth produce ingredients fit to convert into bread, i. e .the staff of life. Some commentators claim that the word לחם does not refer specifically to bread, but to food in general, and G’d was saying to Moses that the people’s food would rain down from the heaven. The meat G’d was going to provide was also included in the line הנני ממטיר לכם לחם מן השמים. We encounter the expression לחם אשה, “food being burned up on the altar,” many times, and it never refers to bread, but to sacrificial meat. (compare Leviticus 3,11; 3,16; Numbers 28,2) Both the selav and the manna materialized for the people as if dropped literally from “heaven.” For some reason, G’d enlarged on the gift of the manna, which was a necessity, whereas He did not elaborate on the selav, which was a luxury.
