Jesus parables sourced in the Old Testament?

How about Prov. 25:6, 7?  “Put not forth thyself in the presence of the king, and stand not in the place of great men: For better it is that be said unto thee, Come up hither; than that thou shouldest be put lower in the presence of the prince whom thine eyes have seen.” 

It brings forth a parable from Jesus, according to Luke 14:7-11: “And he put forth a parable to those which were bidden, when he marked how they chose out the chief rooms; saying unto them, When thou art bidden of any man to a wedding, sit not down in the highest room; lest a more honourable man than thou be bidden of him; And he that bade thee and him come and say to thee, Give this man place; and thou begin with shame to take the lowest room.  But when thou art bidden, go and sit down in the lowest room; that when he that bade thee cometh, he may say unto thee, Friend, go up higher: then shalt thou have worship in the presence of them that sit at meat with thee. For whosoever exalteth himself shall be abased; and he that humbleth himself shall be exalted.”

I ask myself, “Do all of Jesus’ parables have a source in the Old Testament?”
