It's often overlooked because there's so much else in the Passion narrative to think about, but there's a reference to the fact that Jesus was blindfolded by the guards. Here's what Luke says:
Luke 22:63-65: Now the men who were holding Jesus mocked him and beat him; 64 they also blindfolded him and asked him, “Prophesy! Who is it that struck you?” 65 And they spoke many other words against him, reviling him.Why did they blindfold Jesus and mock him about prophesying?
I would like to suggest that it had to do with an ancient interpretation of Isaiah's description of the messiah.
In Isaiah 11 we read a description of a coming Davidic king whom ancient Jews understood as the Messiah, as, for example, the Dead Sea Scrolls attest (cf. e.g., 1Q28b 5).
Isa 11:1-4: There shall come forth a shoot from the stump of Jesse, and a branch shall grow out of his roots. 2 And the Spirit of the Lord shall rest upon him, the spirit of wisdom and understanding, the spirit of counsel and might, the spirit of knowledge and the fear of the Lord. 3 And his delight shall be in the fear of the Lord. He shall not judge by what his eyes see, or decide by what his ears hear; 4 but with righteousness he shall judge the poor, and decide with equity for the meek of the earth; and he shall smite the earth with the rod of his mouth, and with the breath of his lips he shall slay the wicked.The prophecy is very clear that the Messiah will not judge by what he sees or by what he hears. It also describes the Messiah as having powerful breath--it slays the wicked.
That this passage played a key role in ancient Jewish expectations about the coming Messiah is clear from the accounts of Simon bar Kokhba, a Jewish revolutionary of the early second century. Simon convinced many that he was the Messiah and drew quite a following. The Temple had been destroyed, but Simon seems to have promised that he would liberate Jerusalem from the Romans and even get it rebuilt. In fact, the famous Rabbi Aqiba was even counted as one of his followers.
Why was he so popular?
Well, for one thing, according to rabbinic tradition, the famous Aqiba held Simon to be the messiah because he believed Bar Kohkba was able to perform miraculous signs (cf. y. Ta‘an. 68d; also cf. Mishneh Torah, Melakhim 11:3).
Jerome would later testimony that Simon “fanned a lighted blade of straw in his mouth with puffs of breath so as to give the impression that he was spewing out flames” (Rufinus 3.31; PL 23.480). This certainly seems to tap into Isaiah's vision of a Messiah with powerful breath.
What happened to Bar Kohkba? Well, he was eventually revealed as a fraud. Here's the story:
“Bar [Kokhba] reigned two and a half years, and then said to the Rabbis, ‘I am the Messiah.’ They answered, ‘Of Messiah it is written that he smells and judges: let us see whether he [Bar Kokhba] can do so.’ When they saw that he was unable to judge by the scent, they slew him” (cf. also m. Ta‘an. 4:6; b. Git. 57a-b; Lam. Rab. 2:2 §4).Where did the rabbis get the idea that the Messiah would judge by scent and not by seeing or hearing? The most likely answer is that this idea emerged out of Isaiah's prophecy: "he shall not judge by what his eyes see, or decide by what his ears hear… .”
So why was it that Jesus was blindfolded? I would suggest that the Jewish guards were likely mocking Jesus, who refused to give them a spectacle of his power for their amusement. Note by the way that the blindfolded beating of Jesus is closely associated with his standing before Caiaphas who asks him about his messianic identity, which follows next in Luke 22:66-71.
