Isaiah 20:4

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 47:2-3

47:2 Pick up millstones and grind flour!

Remove your veil,

strip off your skirt,

expose your legs,

cross the streams!

47:3 Let your private parts be exposed!

Your genitals will be on display! ² 

I will get revenge;

I will not have pity on anyone,” ³ 

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

[47:3]  ² tn Heb “Your shame will be seen.” In this context “shame” is a euphemism referring to the genitals.

[47:3]  ³ tn Heb “I will not meet a man.” The verb פָּגַע (pagah) apparently carries the nuance “meet with kindness” here (cf. 64:5, and see BDB 803 s.v. Qal.2).
