Yechezkel and the Valley of Dry Bones
Did the dry bones Yechezkel saw really live again? One opinion says they did, and Rabbi Yehudah ben Besaira says he descends from them and has their tefillin.
It discusses a valley of dried human bones that were miraculously resurrected. The Gemara in Sanhedrin (92b) cites a dispute if the incident recorded in Tanach actually took place or if it was a vision that Yechezkel saw in a prophetic state. An opinion there states that, indeed, the very old bones did come to life. They even moved to Israel, married, and had children. Rav explains that the bones belonged to members of the tribe of Ephraim. During the enslavement in Egypt, they made a tragic erroneous miscalculation. They thought that the time for the redemption had already arrived. Therefore, they left Egypt before the correct time. Unfortunately, they were massacred. These individuals received a second chance at life when many years later they were resurrected.
Rebbe Yehuda Ben Besaira opines that the opinion that the bones came back to life, moved to Israel, and married is correct. He states that, in fact, he is actually descended from those very people! Moreover, his grandfather gave him a pair of tefillin that were used by the resurrected people!
