Isaiah 36:12

36:12 But the chief adviser said, “My master did not send me to speak these words only to your master and to you. ¹  His message is also for the men who sit on the wall, for they will eat their own excrement and drink their own urine along with you!” ² 

Isaiah 36:18

36:18 Hezekiah is misleading you when he says, “The Lord will rescue us.” Has any of the gods of the nations rescued his land from the power of the king of Assyria? ³ 

[36:12]  ¹ tn Heb “To your master and to you did my master send me to speak these words?” The rhetorical question expects a negative answer.

[36:12]  ² tn Heb “[Is it] not [also] to the men…?” The rhetorical question expects the answer, “Yes, it is.”

[36:18]  ³ tn Heb “Have the gods of the nations rescued, each his land, from the hand of the king of Assyria?” The rhetorical question expects the answer, “Of course not!”
