At the same time spoke the LORD by Isaiah the son of Amoz, saying,
Go and remove the sackcloth from off your body, and put off your shoes from your feet.
And he did so, walking naked and barefoot.
All Commentaries on Isaiah 20:2 Go To Isaiah 20
Ambrose of Milan
AD 397
Someone perhaps will say, “Was it not disgraceful for a man to walk naked among the people since he must meet both men and women? Must not his appearance have shocked the gaze of all, but especially that of women? Do we not ourselves generally abhor the sight of naked men? And are not men’s private parts covered with clothing that they may not offend the gaze of onlookers by their unsightliness?”
I agree, but you must consider what this act represented and what was the reason for this outward show; it was that the young Jewish youths and maidens would be led away into exile and walk naked, “as my servant Isaiah walked,” he says, “naked and barefoot.” This might have been expressed in words, but God chose to enforce it by an example that the very sight might strike more terror, and what they shrank from in the body of the prophet they might utterly dread for themselves. Wherein lay the greater abhorrence: in the body of the prophet or in the sins of the disbelievers?
