'Pure' in the Bible

But you disowned and denied the Holy and Righteous One and asked for [the pardon of] a murderer to be granted to you.

But as they opposed and spoke injuriously, he shook his clothes, and said to them, Your blood be upon your own head: I am pure; from henceforth I will go to the nations.

Wherefore I take you to record this day, that I am pure from the blood of all men.
