Isaiah 20:3

“And the Lord said, &c.] Here follows the explanation of the sign, and the accommodation of it to the thing signified by it: like as my servant Isaiah hath walked naked and barefoot; not wholly naked, for that would have been very indecent and dangerous indeed; but without his upper garment, as Saul, (<091924>1 Samuel 19:24) and David, (<100614>2 Samuel 6:14,20) or with rent and ragged clothes, and old shoes, as Jarchif400 interprets it, and which might be only when he appeared abroad; and how long he thus walked is not certain, whether only one day, as some, or three days, as others, or three years, which is not said, though our version inclines to it; but the three years next mentioned are…”

“three years--Isaiah's symbolical action did not continue all this time, but at intervals, to keep it before the people's mind during that period [ROSENMULLER]. Rather, join "three years" with "sign," a three years' sign, that is, a sign that a three years' calamity would come on Egypt and Ethiopia [BARNES], (Isa 8:18). This is the only instance of a strictly symbolical act performed by Isaiah. With later prophets, as Jeremiah and Ezekiel, such acts were common. In some cases they were performed, not literally, but only in prophetic vision. wonder--rather, "omen"; conveying a threat as to the future [G. V. SMITH]. upon--in reference to, against.”

“Like as - That is, as Isaiah has gone stripped of his special garment as a prophet, so shall the Egyptians and Ethiopians be stripped of all that they value, and be carried captive into Assyria.’ Hath walked ... three years - A great deal of difficulty has been felt in the interpretation of this place, from the strong improbability that Isaiah should have gone in this manner for a space of time so long as our translation expresses. The Septuagint renders this, ‘As my servant Isaiah hath walked naked and barefoot three years, three years shall be for signs and wonders to the Egyptians and Ethiopians.’ The phrase in the Hebrew, ‘three years,’ “may” either be taken in connection with the…”

“Three years - Not constantly, but when he went abroad among the people, to whom this was appointed for a sign. A sign - When this judgment should come, namely, three years after this prophecy. Isaiah 20:4”

“20:3-4 This symbolic event took place some three years before the fall of Ashdod (see 20:2). Through it, Isaiah became an object lesson for the people (see 8:18).”

“three: Num 14:34; Eze 4:5, Eze 4:6; Rev 11:2, Rev 11:3 a sign: Isa 8:18 upon Egypt: Isa 18:1-7 Isaiah 20:4”

“It is not till Isaiah has carried out the divine instructions, that he learns the reason for this command to strip himself, and the length of time that he is to continue so stripped. "And Jehovah said, As my servant Yesha'yahu goeth naked and barefooted, a sign and type for three years long over Egypt and over Ethiopia, so will the king of Asshur carry away the prisoners of Egypt and the exiles of Ethiopia, children and old men, naked and barefooted, and with their seat uncovered - a shame to Egypt." The expression "as he goeth" (ca'asher hâlac) stands here at the commencement of the symbolical action, but it is introduced as if with a retrospective glance at its duration for three years,…”
