Mattityahu 27:3-5

Orthodox Jewish Bible

³ 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,

⁴ saying Chatati (I have sinned). I have betrayed dam naki (innocent blood). But they said, What is that to us? See to that yourself!

⁵ And Yehudah threw the shiklei kesef (pieces of silver) into the Beis Hamikdash and departed; and, having gone away, Yehudah hanged himself.
