Sense 2: to cause to not understand, to make unable to comprehend

Semantic domains: Understand

Subdomains: Capacity for Understanding

Definition: (an idiom, literally: to blind the eyes) to cause someone to no longer have the capacity for understanding

Notes: Though in some languages there is a close relationship between the eyes and comprehension, in many languages it is simply impossible to use the idiom ‘to blind the eyes’ in speaking of ‘causing someone not to understand.’ The problem becomes particularly difficult in speaking of ‘darkness blinding the eyes’ as in OET JN1 2:11. People can understand how ‘bright light would blind the eyes,’ but it would be strange indeed to think of ‘darkness’ having such an effect. In the context of OET JN1 2:11, the darkness is, of course, not literal darkness but a state of sinfulness. Therefore, in some languages it may be necessary to translate ‘their sinfulness has made it impossible for them to understand’ or ‘because they sin, they cannot understand.’
