Psalm 81, informs you that they refused to listen; and that is why they do not receive the wheat and honey. Has we know honey is symbolic of wisdom that was called to do the count in Rev 13. Psalm 81 speaks of ELIAKIM Joseph-Sophia and how the burden was removed from their shoulders.

"Behold, the former things are come to pass, and new things do I declare: before they spring forth I tell you of them" (Isaiah 42:9).
"I will bring the blind by a way that they knew not; I will lead them in paths that they have not known: I will make darkness light before them, and crooked things straight. These things will I do unto them, and not forsake them" (42:16).
"Let the wilderness and the cities thereof lift up their voice...let the inhabitants of the rock sing, let them shout from the top of the mountains. Let them give glory unto the Lord, and declare his praise in the islands" (42:11-12).
