Albert Barnes Commentary Numbers 16:14

"Moreover thou hast not brought us into a land flowing with milk and honey, nor given us inheritance of fields and vineyards: wilt thou put out the eyes of these men? we will not come up." — Numbers 16:14 (ASV)

Will you put out the eyes of these men? — that is, “blind them to the fact that you keep none of your promises;” “throw dust in their eyes.”
