the ban. Saul looked at the 12 stones, and for each tribe that had followed the law, its stone (on the High Priest's breastplate) shined with its light, and for each tribe that had transgressed, the light of its stone was dim. So Saul knew that the tribe of Benjamin had trespassed in the matter of the ban. The Mishnah reported that with the death of the former prophets, the Urim and Thummim ceased. In this connection, the Gemara reported differing views of who the former prophets were. Rav Huna said they were David, Samuel, and Solomon. Rav Nachman said that during the days of David, they were sometimes successful and sometimes not (getting an answer from the Urim and Thummim), for Zadok consulted it and succeeded, while Abiathar consulted it and was not successful, as reports, "And Abiathar went up."

Rabbah bar Samuel asked whether the report of , "And he (King Uzziah of Judah) set himself to seek God all the days of Zechariah, who had understanding in the vision of God," did not refer to the Urim and Thummim. But the Gemara answered that Uzziah did so through Zechariah's prophecy.

Rav Nachman concluded that the term "former prophets" referred to a period before Haggai, Zechariah, and Malachi, who were latter prophets. And the Jerusalem Talmud taught that the "former prophets" referred to Samuel and David, and thus the Urim and Thummim did not function in the period of the First Temple, either. Rabbi Hanina ben Gamaliel interpreted the words "completely blue (, tekhelet)" in to teach that blue dye used to test the dye is unfit for further use to dye the blue, tekhelet strand of a tzitzit, interpreting the word "completely" to mean "full strength." But Rabbi Joḥanan ben Dahabai taught that even the second dyeing using the same dye is valid, reading the words "and scarlet" (, ushni tolalat) in to
