The Torah in Parashat Vayishlach tells of the mysterious assailant who wrestles with Yaakov the night he crossed the Yabok River as he made his way back toward Canaan after his sojourn in Charan. The word used by the Torah in describing Yaakov’s fight with this assailant is “va-yei’aveik” – “he struggled” – which Targum Onkelos translates into Aramaic as “ve-ishtadal” (32:25).
