When a hero has spiritual leanings, their last words should contain some moral lesson or some other inspiration. This is why final words can make (that is, immortalize) or break a hero for future generations. Abraham’s last words about the lamb are unique for what they
don’t say—either an untruth or the truth. Abraham came up with the perfect non-answer that still technically answers the question. Indeed, God will provide the lamb, but there is no saying whether Isaac (who was a literal gift from God) isn’t that lamb. Isaac doesn’t see or understand this, though, and is content with Abraham’s words.
