'Kills' in the Bible

“You have heard that it was said to the men of old, ‘You shall not murder,’ and ‘Whoever murders shall be guilty before the court.’

And He said to them, “My soul is deeply grieved and overwhelmed with sorrow, to the point of death; remain here and keep watch.”

They will put you out of the synagogues and make you outcasts. And a time is coming when whoever kills you will think that he is offering service to God.

He has qualified us [making us sufficient] as ministers of a new covenant [of salvation through Christ], not of the letter [of a written code] but of the Spirit; for the letter [of the Law] kills [by revealing sin and demanding obedience], but the Spirit gives life.
