<p>18:20 <i>You know the commandments: Do not commit adultery. Do not kill. Do not steal. Do not bear false witness. Honour your father and mother</i>- Harry Whittaker makes an interesting but not totally convincing case that the rich young man here was Barnabas and these commands were very relevant to him as a Levite- see&nbsp;<i>Studies in the Gospels&nbsp;</i>chapter 148. Paul's references to the Gospels suggests that he had carefully meditated upon the passages to which he consciously alludes. The fact and way in which he&nbsp;<i>alludes</i>&nbsp;rather than quotes verbatim reflects the fact he had thought through and absorbed the teaching of the passages rather than learning them parrot fashion. Here the Lord Jesus combines two quotations from the Law: Ex. 20:12-16 followed by Lev. 19:18. Paul, in a different context, to prove a different point, combines those same two passages, although separating them by a brief comment (Rom. 13:9). This surely indicates that he had meditated upon how his Lord was using the Law, and mastered it so that he could use it himself.</p>
