Him that is taught in the word. — He who receives instruction in the truths of the gospel. Even at this early date there seems to have been a more or less organised system of instruction in the Church. Teaching was regarded as a separate function, though those who took part in it do not seem as yet to have formed a separate class. See Acts 13:1; Romans 12:7; 1 Corinthians 12:28-29; Ephesians 4:11; James 3:1 (“masters” should be rather “teachers”). The teacher was dependent on the alms of his scholars.
Communicate... in all good things. — Let him impart or share with his teacher in all those temporal goods with which God has blessed him. The teacher would not receive any settled and regular payment, but the scholar would make him presents — many of them, probably, in kind — so as to relieve him from the care of providing for his own livelihood, and so give him more leisure for his work of teaching.
