Mat 9:6 But that you may know that the Son of man has power on earth to forgive sins, Arise, take up your bed, and go to your house.

The term translated as "know" is eido, which means literally "to see."

The term translated as "power" is exousia, which means "authority," "power of choice," and "resources."

"Forgive sins" is aphiemi hamartia means "to send away failure."

The world translated as "bed" is kline, which means "that on which one lies," but it also means a "grave-niche."

Here, Christ fulfills the promise made in the last verse. He literally shows the scribes his power so that they can see it. He demonstrate that he has the power to put people's mistakes behind them by giving this man the power to walk, which means to live and make progress. He metaphorically tells the man to pick up his that bed (that was his grave) and go to his house (oikos, which also means "family").
