Jeremiah 9:23-26

The LORD says: Don't brag about your wisdom or strength or wealth. If you feel you must brag, then have enough sense to brag about worshiping me, the LORD. What I like best is showing kindness, justice, and mercy to everyone on earth. Someday I will punish the nations of Egypt, Edom, Ammon, and Moab, and the tribes of the desert. The men of these nations are circumcised, but they don't worship me. And it's the same with you people of Judah. Your bodies are circumcised, but your hearts are unchanged.
