Does Jewish tradition teach us anything that might explain the origin of the name Yisha'yahu/Isaiah/יְשַׁעְיָהוּ?
I am referring to the prophet who bore the name. If his name means, as it seems to, "G-d is salvation," what might be the meaning behind it? From what, exactly, might his parents have been hoping to be saved? Based on what we know from the biblical narrative and Jewish commentary, was the political instability in the House of David felt throughout the land at the time of his birth? Was the eventual invasion of the Assyrian army seen as inevitable or likely? Was there something else going on? Or does it just seem to be a nice name?
