And they brought to him a man who was deaf and had a speech impediment, and they begged him to lay his hand on him.
Mark 7:32

#yeshua healed this man's hearing and speech. Immediately the man spoke clearly with no impediment. His speech impediment was probably caused by his impaired hearing. Even if Yeshua healed a physical defect like a cleft palate, he also had to transform--not just heal--his mind and musculature or else the man would have spent years learning to speak properly.
