IMHO Jesus was rather quoting from Psalms.
Yes, this reflects Psalm 37:10-11...
A little while longer, and the wicked will be no more,
search his place well, he will not be there;
but the humble shall have the land for their own
to enjoy untroubled peace.
..and also Proverbs 2:20-22
So you will pursue the way of good men,
persisting in the in the paths of the viruous.
For the land will be for honest men to live in,
the innocent will have it for their home;
while the wicked will be cut off from the land,
and the faithless rooted out of it.
Nothing there about "paradise earth", nor mention of any special "class" to rule over the land. This theme recurs in Matthew 23:12-13, from another point of view. Instead of solace for the downtrodden, this version is a warning to their oppressors:
Anyone who exalts himself will be humbled, and anyone who humbles himself will be exalted.
Alas to you, scribes and Pharisees, you hypocrites! You who shut up the kingdom of heaven in men's faces, neither going in yourself nor allowing others to go in who want to.
