Jeremiah 9:23–24

God says what is worth boasting in: knowing him, who does steadfast love and justice

23Thus says YHWH: “Let not the wise man boast in his wisdom, and let not the mighty man boast in his might; let not the rich man boast in his riches;

24but in this let the one who boasts boast: in having understanding and knowing me, that I am YHWH, who practices loyal love, justice, and righteousness in the earth; for in these things I delight, declares YHWH.

In its context

21For death has come up through our windows; it has entered our palaces, to cut off the child from the street, the young men from the squares.

22Speak: “Thus declares YHWH: ‘The corpses of human beings will fall like dung on the face of the field, and like a sheaf behind the reaper, with no one to gather them.’”

…

25Look, days are coming, declares YHWH, when I will punish all who are circumcised in the foreskin:

26Egypt and Judah and Edom and the sons of Ammon and Moab and all who are clipped at the temples, who live in the wilderness; for all the nations are uncircumcised, and all the house of Israel are uncircumcised in heart.”
