In short, the OP observes what appears to be a contemporary instance in which Nelson creates a revelation through exaggeration. Nelson claims to have read literally everything on the topic of "Israel," and only recently through interaction with not one, but two Hebrew scholars, was shown that Israel means "let God prevail." And yet, the definition in the Bible Dictionary of the approved LDS standard works for Israel is, "One who prevails with God or Let God prevail*.*"
So I just wonder, which fib came before this particular "delight"? Was it the fib about having read "every" scripture related to Israel? Or was it the fib about the two unnamed Hebrew scholars who assisted Nelson with the arduous task of looking up the definition of Israel?
Well, I mean, he can't possibly do what it takes to learn the actual Hebrew, being a lazy learner prophet...
