Num 14:20-23
20 GOD said, "I forgive them, honoring your words. 21 But as I live and as the Glory of GOD fills the whole Earth — 22 not a single person of those who saw my Glory, saw the miracle signs I did in Egypt and the wilderness, and who have tested me over and over and over again, turning a deaf ear to me — 23 not one of them will set eyes on the land I so solemnly promised to their ancestors. No one who has treated me with such repeated contempt will see it.

Why have I never heard a sermon on this? It’s a key point in the Bible! Are we turning a deaf ear?
