Isaiah 20:3-4

20:3 Later the Lord explained, “In the same way that my servant Isaiah has walked around in undergarments and barefoot for the past three years, as an object lesson and omen pertaining to Egypt and Cush, 20:4 so the king of Assyria will lead away the captives of Egypt and the exiles of Cush, both young and old. They will be in undergarments and barefoot, with the buttocks exposed; the Egyptians will be publicly humiliated. ¹ 

Isaiah 58:7

58:7 I want you ²  to share your food with the hungry

and to provide shelter for homeless, oppressed people. ³ 

When you see someone naked, clothe him!

Don’t turn your back on your own flesh and blood! ⁴ 

[20:4]  ¹ tn Heb “lightly dressed and barefoot, and bare with respect to the buttocks, the nakedness of Egypt.”

[58:7]  ¹ tn Heb “Is it not?” The rhetorical question here expects a positive answer, “It is!”

[58:7]  ² tn Heb “and afflicted [ones], homeless [ones] you should bring [into] a house.” On the meaning of מְרוּדִים (mÿrudim, “homeless”) see HALOT 633 s.v. *מָרוּד.
