The Written Law and the Oral Law are inseparable companions. Both were presented to Moses at Sinai; neither can stand without the other. The Written Law is the foundation. The Mishnah was the first portion of its oral elucidation to be commited to writing. The Artscroll Mishnah Series with Yad Avraham commentarybrings the text to life as it is developed and clarified by contending minds in the study hall.
