Jeremiah 9:22-26

Speak, “Thus says the LORD, ‘The dead bodies of men will fall like dung on the open field, And like sheaves [of grain] behind the reaper, And no one will gather them.’ ” [Jer 8:2] Thus says the LORD, “Let not the one who is wise and skillful boast in his insight; let not the one who is mighty and powerful boast in his strength; let not the one who is rich boast in his [temporal satisfactions and earthly] abundance; but let the one who boasts boast in this, that he understands and knows Me [and acknowledges Me and honors Me as God and recognizes without any doubt], that I am the LORD who practices lovingkindness, justice and righteousness on the earth, for in these things I delight,” says the LORD. [1 Cor 1:31; 2 Cor 10:17] “Behold, the days are coming,” says the LORD, “when I will punish all who are circumcised [physically] and yet uncircumcised [spiritually]— [Rom 2:25-29] Egypt and Judah, and Edom and the sons of Ammon, and Moab and all those who live in the desert who clip off the hair on their temples; for all these nations are uncircumcised (sinful, impure), and all the house of Israel are uncircumcised in heart.”
