51"Have you understood all these things?" They said to Him, "Yes." 52And Jesus said to them, "Therefore every scribe who has become a disciple of the kingdom of heaven is like a head of a household, who brings out of his treasure things new and old."
Mat_13:52 "every scribe who has become a disciple" A scribe was a legal expert in the oral and written Law (see Special Topic at Mat_12:38). A believing scribe will be able to draw truths from the Old Testament as well as see the fulfillments in Jesus' teachings (cf. Rom_4:23-24; Rom_15:4; 1Co_10:6; 1Co_10:11; 2Ti_3:16). It is possible Matthew is characterizing himself!
