The Aqedath Jishaq is a poem in Yiddish composed in the period 1558 to 1578. It is based on the story in the Bible in Genesis Chapter 22 about how God ordered Abraham to take his son up to the top of Mount Moriah and sacrifice him. Just as Abraham was about to kill his son, God called the whole thing off. The cover shows an etching by Rembrandt from 1655 depicting an angel stopping Abraham when he is about to kill Isaac.
