A type prefiguring the shameful captivity of Egypt and Ethiopia.
Isaiah 20:1 In the year that Tartan entered Ashdod, when Sargon king of Assyria, sent him,and he fought against Ashdod and captured it, Isaiah 20:2 At that time, spake Yahweh, through Isaiah son of Amoz, saying, Go, and loose the sackcloth from off thy loins, And, thy sandal, draw thou off from thy foot,And he did so, walking disrobed and barefoot. Isaiah 20:3 Then said Yahweh,As my servant Isaiah, hath walked, disrobed and barefoot, three years, as a sign and a wonder, against Egypt and against Ethiopia, Isaiah 20:4 So, shall the king of Assyria lead away the captives of Egypt, and the exiles of Ethiopia, young and old, disrobed and barefoot,with their persons behind uncovered, the shame of Egypt. Isaiah 20:5 Thus shall they be confounded, and turn pale,For Ethiopia, their expectation, and, For Egypt, their boast; Isaiah 20:6 And the inhabitant of this shore, shall exclaim, in that day, Lo! such, is our expectation, whereunto we fled for help, that we might be delivered from the presence of the king of Assyria! How then shall, we, escape?
