Gospel of Luke: The Greek Word for Riches

The Greek Word (plusios) which Luke uses in his Gospel is NOT present in the OT, NOR the Gospel of John and rare in Mark and Matthew. From the list of verses below it can be seen that Luke portrays that difficulty of the rich entering the Kingdom of Heaven, the one verse from Mark that is common to Matthew and Luke. 

One might say that Luke illustrates that nothing is impossible with God in the story of Zacheus. Luke also transmits Mark's story about the poor woman in the Temple which Matthew does not. However, neither Mark nor Luke have Matthew's story about Joseph of Arimathea. 

Because of the presence of "camel" metaphor, I think we can say that Luke's teaching was in the mainstream of early Christianity. However, his repeated emphasis upon this teaching suggests that he wrote in a time and place where "riches" and/or its inverse, "the poor" might have been a more important topic than for Mark, Matthew, John.

But woe to you that are rich: for you have your consolation. (Luke 6:24 DRA) Woe to you that are filled: for you shall hunger. Woe to you that now laugh: for you shall mourn and weep.Woe to you when men shall bless you: for according to these things did their fathers to the false prophets.

And he spoke a similitude to them, saying: The land of a certain rich man brought forth plenty of fruits. (Luke 12:16 DRA) And he thought within himself, saying: What shall I do, because I have no room where to bestow my fruits?  And he said: This will I do: I will pull down my barns and will build greater; and into them will I gather all things that are grown to me, and my goods.

And he said to him also that had invited him: When thou makest a dinner or a supper, call not thy friends, nor thy brethren, nor thy kinsmen, nor thy neighbours who are rich; lest perhaps they also invite thee again, and a recompense be made to thee. (Luke 14:12 DRA) But when thou makest a feast, call the poor, the maimed, the lame, and the blind;

And he said also to his disciples: There was a certain rich man who had a steward: and the same was accused unto him, that he had wasted his goods. (Luke 16:1 DRA)

There was a certain rich man, who was clothed in purple and fine linen; and feasted sumptuously every day. (Luke 16:19 DRA) Desiring to be filled with the crumbs that fell from the rich man's table, and no one did give him; moreover the dogs came, and licked his sores. (Luke 16:21 DRA) And it came to pass, that the beggar died, and was carried by the angels into Abraham's bosom. And the rich man also died: and he was buried in hell. (Luke 16:22 DRA)

21 Who said: All these things have I kept from my youth. Which when Jesus had heard, he said to him: Yet one thing is wanting to thee: sell all whatever thou hast, and give to the poor, and thou shalt have treasure in heaven: and come, follow me. He having heard these things, became sorrowful; for he was very rich. (Luke 18:23 DRA)

For it is easier for a camel to pass through the eye of a needle, than for a rich man to enter into the kingdom of God. (Luke 18:25 DRA)  Then Jesus said to his disciples: Amen, I say to you, that a rich man shall hardly enter into the kingdom of heaven. (Matthew 19:23 DRA) And again I say to you: It is easier for a camel to pass through the eye of a needle, than for a rich man to enter into the kingdom of heaven. (Matthew 19:24 DRA) It is easier for a camel to pass through the eye of a needle, than for a rich man to enter into the kingdom of God. (Mark 10:25 DRA)

And behold, there was a man named Zacheus, who was the chief of the publicans, and he was rich. (Luke 19:2 DRA) And he sought to see Jesus who he was, and he could not for the crowd, because he was low of stature. And running before, he climbed up into a sycamore tree, that he might see him; for he was to pass that way.

And looking on, he saw the rich men cast their gifts into the treasury. (Luke 21:1 DRA) And he saw also a certain poor widow casting in two brass mites.  And he said: Verily I say to you, that this poor widow hath cast in more than they all: And Jesus sitting over against the treasury, beheld how the people cast money into the treasury, and many that were rich cast in much. (Mark 12:41 DRA)

And when it was evening, there came a certain rich man of Arimathea, named Joseph, who also himself was a disciple of Jesus. (Matthew 27:57 DRA)
