Blindness.
Used metaphorically to describe the state of man by nature under the influence of Satan, 2 Corinthians 4:4; also a professing Christian who hates his brother, 1 John 2:11; also the state of Israel in their heartless profession, Matthew 23:16-26; and the judicial blindness on Israel. John 12:40. In Romans 11:7, Romans 1:11; 2 Corinthians 1:3; Ephesians 4:18, it is rather 'obdurateness or hardness,' from pwrow,'to harden.'
