And He replied: "Go and tell this people, 'Be ever hearing, but never understanding; be ever seeing, but never perceiving.' Make the hearts of this people calloused; deafen their ears and close their eyes. Otherwise they might see with their eyes, hear with their ears, understand with their hearts, and turn and be healed."
Moses summoned all Israel and proclaimed to them, "You have seen with your own eyes everything the LORD did in Egypt to Pharaoh, to all his officials, and to all his land. You saw with your own eyes the great trials, and those miraculous signs and wonders. Yet to this day the LORD has not given you a mind to understand, eyes to see, or ears to hear.
Significance
The wisdom theme connects Isaiah 6 and Deuteronomy 29, revealing God's order for creation and life. Wisdom personified in the OT finds ultimate expression in Christ, who is 'the wisdom of God' (1 Cor 1:24, 30), in whom 'are hidden all the treasures of wisdom and knowledge' (Col 2:3).
