Tableview reuse and imageView show wrong image in swift

Question

I have a chat app, but I face a problem that about cell reuse.
My cell has imageView, and other label.
When I have new message, and I enter the chat view.
My imageView looks something wrong.
The imageView will show me two the same image.
What's wrong about my situation?
Thanks.

Question Update

sorry, I print indexPath.row in "cellForRowAt" and It also prints new message indexpathRow again like following message.

==) Index.row: 4
==) Index.row: 2
==) Index.row: 3
==) Index.row: 4
