Mattityahu 27:2-10

And having performed the akedah (binding), they led him away, and delivered him up to Pilate the Governor. Then when Yehudah, who had betrayed Moshiach, saw that Yehoshua had been condemned, he felt remorse and returned the sheloshim shiklei kesef (thirty pieces of silver) to the Rashei Hakohanim and the Zekenim, saying Chatati (I have sinned). I have betrayed dahm naki (innocent blood). But they said, What is that to us? See to that yourself! And Yehudah threw the shiklei kesef (pieces of silver) into the Beis Hamikdash and departed; and, having gone away, Yehudah hanged himself. And the Rashei Hakohanim took the shiklei kesef and said, It is asur (forbidden) to put these into the Beis Hamikdash otzar (treasury), vi-bahlt (since) it is blood money. And they took counsel together and they bought the Potterʼs Field as a beis hakevoros (cemetery) for zarim (foreigners). For this reason that field has been called the Sadeh HaDahm (Field of Blood) to this day. Then that which was spoken through Yirmeyah HaNavi was fulfilled, saying, And they took the SHELOSHIM KASEF (thirty pieces of silver), HAYEKAR (the price) of the one whose price had been set by the Bnei Yisroel. And they gave them for the potters field as HASHEM directed — Zech 11:12-13.
