Jeremiah 9:25-26
9:25 The Lord says, “Watch out! The time is soon coming when I will punish all those who are circumcised only in the flesh.
9:26 That is, I will punish the Egyptians, the Judeans, the Edomites, the Ammonites, the Moabites, and all the desert people who cut their hair short at the temples. I will do so because none of the people of those nations are really circumcised in the Lord’s sight. Moreover, none of the people of Israel are circumcised when it comes to their hearts.”
Jeremiah 13:23
13:23 But there is little hope for you ever doing good,
you who are so accustomed to doing evil.
Can an Ethiopian change the color of his skin?
Can a leopard remove its spots?
