At the same time spoke the LORD by Isaiah the son of Amoz, saying, Go and loose the {d} sackcloth from off thy loins, and put off thy shoe from thy foot. And he did so, walking naked and barefoot.

(d) Which signifies that the prophet lamented the misery that he saw prepared before the three years that he went naked and barefooted.

Wesley's Notes

20:2 Sackcloth - Which he wore in token of his grief for the calamities that were already come upon Israel, and were coming upon Judah. Naked - Not wholly naked, but without his upper garment, as slaves and prisoners used to do, whose posture he was to represent. Bare - foot - After the manner of mourners and captives.

King James Translators' Notes

Jamieson-Fausset-Brown Bible Commentary

2. by-literally, "by the hand of" (compare Eze 3:14).

sackcloth-the loose outer garment of coarse dark hair-cloth worn by mourners (2Sa 3:31) and by prophets, fastened at the waist by a girdle (Mt 3:4; 2Ki 1:8; Zec 13:4).

naked-rather, "uncovered"; he merely put off the outer sackcloth, retaining still the tunic or inner vest (1Sa 19:24; Am 2:16; Joh 21:7); an emblem to show that Egypt should be stripped of its possessions; the very dress of Isaiah was a silent exhortation to repentance.

Matthew Henry's Concise Commentary

20:1-6 The invasion and conquest of Egypt and Ethiopia. - Isaiah was a sign to the people by his unusual dress, when he walked abroad. He commonly wore sackcloth as a prophet, to show himself mortified to the world. He was to loose this from his loins; to wear no upper garments, and to go barefooted. This sign was to signify, that the Egyptians and Ethiopians should be led away captives by the king of Assyria, thus stripped. The world will often deem believers foolish, when singular in obedience to God. But the Lord will support his servants under the most trying effects of their obedience; and what they are called upon to suffer for his sake, commonly is light, compared with what numbers groan under from year to year from sin. Those who make any creature their expectation and glory, and so put it in the place of God, will, sooner or later, be ashamed of it. But disappointment in creature-confidences, instead of driving us to despair, should drive us to God, and our expectation shall not be in vain. The same lesson is in force now; and where shall we look for aid in the hour of necessity, but to the Lord our Righteousness, throne of grace, and serving with each other in the same business of religion, should end all disputes, and unite the hearts of believers to each other in holy love.
