(… لِمَ تَلْبِسُونَ …) (…why do you confuse …): They mix the right with the wrong and conceal the truth while they know it. The description of Prophet Muhammad (saws) in the Torah is as stated by Abdallah bin Salam (may Allah be pleased with him):

“When I saw him, I have recognized him as easy as I recognize my son. And I recognize Muhammad more”.
