'Blindness' in the Bible

They struck (punished) the men who were at the doorway of the house with blindness, from the young men to the old men, so that they exhausted themselves trying to find the doorway.

The Lord will strike you with madness and with blindness and with bewilderment of heart and mind;

When the Arameans came down to him, Elisha prayed to the Lord and said, “Please strike this people (nation) with blindness.” And God struck them with blindness, in accordance with Elisha’s request.

You will harden their hearts;Your curse will be upon them.

In that day,” declares the Lord, “I will strike every horse with panic and his rider with madness; but I will open My eyes and watch over the house of Judah, and will strike every horse of the [opposing] nations with blindness.

for their [moral] understanding is darkened and their reasoning is clouded; [they are] alienated and self-banished from the life of God [with no share in it; this is] because of the [willful] ignorance and spiritual blindness that is [deep-seated] within them, because of the hardness and insensitivity of their heart.

On the other hand, I am writing a new commandment to you, which is true and realized in Christ and in you, because the darkness [of moral blindness] is clearing away and the true Light [the revelation of God in Christ] is already shining.
