The 15th century Spanish commentator Isaac ben Moses Arama read the angel’s request in for Jacob to let him go as simply another way of asking Jacob why he was wasting his time detaining the angel, when he should have been busy preparing gifts for Esau. Isaac ben Moses Arama taught that Jacob’s request to know the angel’s name meant that Jacob wanted to know who had the power to inflict such damage on his hip joint. The angel told Jacob that it was not the angel’s name that mattered, since the ability to inflict damage was not rooted in the identity of the angel, but rather, the mission of the angel was the important thing.
