GEN1120 Avoth de R. Nathan (Chap 7) adds that he built large mansions by the wayside and left provisions there for the sake of passersby (see Sotah 10a).   How worthy would it be for man to learn this virtue from Abraham our forefather!   Every person should arrange to have a guest rom. When his guest leaves in the morning, he will, then, naturally fulfill the mitzvah of escorting him.   The letters of the word eshel (tamarisk tree) are initials: aleph stands for achilah, eating; shin for shethiah, drinking; lamed for leviah, escorting.   Others have lamed for linah, lodging.   Chazal have stated “and if one is unable to fulfill the mitzvah of providing the guest with food and drink properly, is he therefore not to perform the mitzvah of providing lodging and escorting?” AHAVCH 197-8 (Continued at [[DEUT1034]] Deuteronomy 20:7 shed AHAVCH 198)
