At Matt 26: 63-65 we see:
"But Jesus was silent. And the high priest said to him, “I adjure you by the living God, tell us if you are the Christ, the Son of God.” Jesus said to him, “You have said so. But I tell you, hereafter you will see the Son of man seated at the right hand of Power, and coming on the clouds of heaven.” Then the high priest tore his robes, and said, “He has uttered blasphemy. Why do we still need witnesses? You have now heard his blasphemy."
I wish to know when the practice of tearing one's own garments in order to show protest, especially when one was witnessing apparent blasphemy, started among the Jews. Did such a practice have its origin in the scriptures ?
