Moses – Moshe Rabeinu – lived with a disability.
The Sages recount that as an infant and prince in Egypt, the future hero of the Passover story had a choice to take either gold or hot coal. The Egyptians were testing the baby; had he taken the gold, he would have been considered a threat to Pharaoh. An angel directed Moses to the hot coal – which he put in his mouth. As a result of his burned tongue, he had a stutter.
As Hashem recruited him to lead the people of Israel, Moses said, “I am slow of speech and slow of tongue.”
