kammuo

ἐκάμμυσαν: [1 verse](verb, 3rd, pl, aor, ind) "Closed" is from kammuo, which means specifically "to close or shut the eyes."  - The "they shall see" is from the common verb for "to see" and "to understand." It is not in the future tense, as in the KJV, but in a tense that indicates something that might probably happen at a specific time in the past present and future.
