Jer 5:1

“After the address of the Lord in which he commanded, "go throughout Jerusalem," and so on, the prophet addresses the Lord in return: "Lord, your eyes look for faith," which is ʾemûnā in Hebrew, referring not to the works of the Jews, in which they exulted according to ceremonies of the law, but to the faith of Christians, through which we are saved by faith. In this chapter, therefore, we learn that supplications are brought for the correction of our faults. This is why he says, "You struck them, and they did not grieve; you wore them out, but they refused to accept discipline." For Jerusalem was emended through many torments and chastisements and was found to have no shame for their faults after all of this, but with rock-hard shamelessness on their brow, they would not convert to the better way.”

“(Chapter 5 - Verse 1, 2) Go around the streets of Jerusalem and look, observe, and search its squares, whether you find a man who does justice and seeks faithfulness. I will be merciful to him. But even if, by the living Lord, they say and falsely swear this. Great is the love of justice, as God did not deliver the city (Genesis 18) according to the request of Abraham and the response of God for the sake of ten righteous men, but if He finds even one in the now perishing Jerusalem who does justice and seeks faithfulness (or, as Symmachus translated, truth), then God will have mercy on Jerusalem. And because it could happen that some would be found among the people who would feign the worship of God and swear by God, this is prevented so that God is not pleased by empty words but by the truth of faith, and He says: I do not love those who swear by me and swear falsely, but rather those whose hearts and lips are in agreement.”
