'Disgraceful Thing' in the Bible

because they have done a disgraceful thing in Israel, and they have committed adultery with the wives of their neighbors, and they have spoken words in my name, lies that I have not commanded them, and I [am] he who knows, and [I am] a witness,' {declares} Yahweh."

For after we turned away from you we repented. After we came to our senses we beat our breasts in sorrow. We are ashamed and humiliated because of the disgraceful things we did previously.'
