Jamieson, Fausset and Brown on Matthew 10:8

8. Heal the sick, cleanse the lepers, raise the dead, cast out devils--(The italicized clause--"raise the dead"--is wanting in many manuscripts). Here we have the first communication of supernatural power by Christ Himself to His followers--thus anticipating the gifts of Pentecost. And right royally does He dispense it.

freely ye have received, freely give--Divine saying, divinely said! (Compare De 15:10, 11; Ac 3:6)--an apple of gold in a setting of silver (Pr 25:11). It reminds us of that other golden saying of our Lord, rescued from oblivion by Paul, "It is more blessed to give than to receive" (Ac 20:35). Who can estimate what the world owes to such sayings, and with what beautiful foliage and rich fruit such seeds have covered, and will yet cover, this earth!
