When he was seated (5:1): It was the custom for Jewish rabbisto be seated while teaching (see Mk 4:1; 9:35; Lk 4:20; 5:3; Jn 8:2).[bsg_ref id="81" vol="" page="1444"]
The Beatitudes are named from the Latin word beatus meaning blessed...The Greek term means “happy, fortunate.”[bsg_ref id="70" vol="" page="1418"]
Salt (5:13): Whereas the Phoenicians obtained quantities of salt from the Mediterranean by evaporation in salt-pans, the Hebrews had access to an unlimited supply on the shores of the Dead Sea (Zp. ii. 9) and in the hill of Salt (Jebel Usdum), a 15-square-mile elevation at the SW corner of the Dead Sea...Such salt was of the rock or fossil variety, and, because of impurities and the occurrence of chemical changes, the outer layer was generally lacking in flavour. The reference in Mt. v. 13 is to this latter, much of which was discarded as worthless. Salt was valued as a preservative and for seasoning food. It was often used among Oriental peoples for ratifying agreements, so that salt became the symbol of fidelity and constancy.[bsg_ref id="80" vol="" page="1125"]
