'Blush' in the Bible

“Were they ashamed because of the abomination they have done?They were not even ashamed at all;They did not even know how to blush.Therefore they shall fall among those who fall;At the time that I punish them,They shall be cast down,” says the Lord.

“Were they ashamed because of the abomination they had done?They certainly were not ashamed,And they did not know how to blush;Therefore they shall fall among those who fall;At the time of their punishment they shall be brought down,”Says the Lord.
