Isaiah 20:2-4

ECB(i) 2 at the same time, Yah Veh words by the hand of Yesha Yah the son of Amos, saying, Go and loosen the sackcloth from your loins, and pull your shoe from your foot. - and thus he works, walking naked and unshod. 3 And Yah Veh says, As my servant Yesha Yah walks naked and unshod three years for a sign and omen upon Misrayim and upon Kush; 4 thus the sovereign of Ashshur drives away the Misrayim prisoners and the Kushi exiles - lads and aged, naked and unshod, even with their buttocks stripped to the nakedness of Misrayim.
