“right before their eyes.” The Hebrew text is literally “eye in eye,” which is an idiom for “right before your eyes.” The only other occurrence of “eye to eye” in the Bible is Isaiah 52:8, which speaks of how the watchmen in Jerusalem will shout for joy when Yahweh returns to Zion, which He does by sending the Messiah, His Son.
