Luke's gospel on Rich and Poor.

 Luke ch.6:20-26KJV"20And he lifted up his eyes on his disciples, and said, Blessed be ye poor: for yours is the kingdom of God. 21Blessed are ye that hunger now: for ye shall be filled. Blessed are ye that weep now: for ye shall laugh. 22Blessed are ye, when men shall hate you, and when they shall separate you from their company, and shall reproach you, and cast out your name as evil, for the Son of man's sake. 23Rejoice ye in that day, and leap for joy: for, behold, your reward is great in heaven: for in the like manner did their fathers unto the prophets.

24But woe unto you that are rich! for ye have received your consolation. 25Woe unto you that are full! for ye shall hunger. Woe unto you that laugh now! for ye shall mourn and weep. 26Woe unto you, when all men shall speak well of you! for so did their fathers to the false prophets."

Strong's Exhaustive Concordance

beggar, poor.

From ptosso (to crouch); akin to ptoeo and the alternate of pipto); a beggar (as cringing), i.e. Pauper (strictly denoting absolute or public mendicancy, although also used in a qualified or relative sense; whereas penes properly means only straitened circumstances in private), literally (often as noun) or figuratively (distressed) -- beggar(-ly), poor.:

Taken literally Jesus said happy/ blessed are you beggars. There were certainly no literal beggars among the twelve apostles that He had just chosen. So what kind of beggar does JEHOVAH bless ,the parallel account of Matthew is helpful. 

Matthew ch.5:3NIV"“Blessed are the poor in(Beggars for the) spirit,

for theirs is the kingdom of heaven."

The simple fact of the matter is that when it comes to the spiritual we are all poor. Some are aware of that critical poverty in their own particular case and are eagerly pursuing the one source that can alleviate it, our Lord promises that all such are due for a blessing.

Others imagine themselves to be "rich" but Paul warns that our evaluation of ourselves is of no consequence

1Corinthians ch.4:4NIV"My conscience is clear, but that does not make me innocent. It is the Lord who judges me."

So the "rich" are "poor" in JEHOVAH'S eyes and the "poor" are "rich" in JEHOVAH'S eyes.
