Still don't see where it says no one else was healed. I do see that "strange things," is plural. Definitely don't want to beat a dead horse, especially over a minor interpretational difference, and when your point is definite in another place in scripture.
Let me flip the horse over for one last effort.
Luke - a Greek writes this literal account.
Luke 5:17 Now it happened on a certain day, as He was teaching, that there were Pharisees and teachers of the law sitting by, who had come out of every town of Galilee, Judea, and Jerusalem. And the power of the Lord was present to heal them. 18 Then behold, men brought on a bed a man who was paralyzed, whom they sought to bring in and lay before Him. 19 And when they could not find how they might bring him in, because of the crowd, they went up on the housetop and let him down with his bed through the tiling into the midst before Jesus.
20 When He saw their faith, He said to him, “Man, your sins are forgiven you.”
21 And the scribes and the Pharisees began to reason, saying, “Who is this who speaks blasphemies? Who can forgive sins but God alone?”
22 But when Jesus perceived their thoughts, He answered and said to them, “Why are you reasoning in your hearts? 23 Which is easier, to say, ‘Your sins are forgiven you,’ or to say, ‘Rise up and walk’? 24 But that you may know that the Son of Man has power on earth to forgive sins”—He said to the man who was paralyzed, “I say to you, arise, take up your bed, and go to your house.”
25 Immediately he rose up before them, took up what he had been lying on, and departed to his own house, glorifying God. 26 And they were all amazed, and they glorified God and were filled with fear, saying, “We have seen strange things today!”
The whole interaction was with 'them'. Luke who wrote literally mentions this whole interaction and you believe Luke decided to not mention the whole purpose of God's power being shown? You have an interesting viewpoint.
