(Exodus 12:10) "And you shall not leave over anything of it until the morning, and what is left over of it until the morning, in fire shall you burn it." What is the intent of (the seemingly redundant) "until the morning"? To set a bound for the morning of morning (i.e., that he may eat it (only) until the rising of the morning star, and not until sunrise). Variantly: What is the intent of "until morning"? To teach that it is not burned until the eve of the sixteenth (of Nissan).
