His writings (toi ekeinou grammasin). Dative case with pistuete. See Luke 16:31 for a like argument. The authority of Moses was the greatest of all for Jews. There is a contrast also between writings (grammasin, from grapw, to write) and words (rhmasin, from eipon). Gramma may mean the mere letter as opposed to spirit ( 2 Corinthians 3:6 ; Romans 2:27Romans 2:29 ; Romans 7:6 ), a debtor's bond ( Luke 16:6 ), letters or learning ( John 7:15 ; Acts 26:24 ) like agrammatoi for unlearned ( Acts 4:13 ), merely written characters ( Luke 23:38 ; 2 Corinthians 3:7 ; Galatians 6:11 ), official communications ( Acts 28:21 ), once iera grammata for the sacred writings ( 2 Timothy 3:15 ) instead of the more usual ai agiai grapai. Graph is used also for a single passage ( Mark 12:10 ), but biblion for a book or roll ( Luke 4:17 ) or biblo ( Luke 20:42 ). Jesus clearly states the fact that Moses wrote portions of the Old Testament, what portions he does not say. See also Luke 24:27Luke 24:44 for the same idea. There was no answer from the rabbis to this conclusion of Christ. The scribes (oi grammatei) made copies according to the letter (kata to gramma).
