'Kill' in the Bible

Now Absalom had commanded his servants, saying, Mark ye now when Amnon's heart is merry with wine, and when I say unto you, Smite Amnon; then kill him, fear not: have not I commanded you? be courageous, and be valiant.

And, behold, the whole family is risen against thine handmaid, and they said, Deliver him that smote his brother, that we may kill him, for the life of his brother whom he slew; and we will destroy the heir also: and so they shall quench my coal which is left, and shall not leave to my husband neither name nor remainder upon the earth.

And Absalom answered Joab, Behold, I sent unto thee, saying, Come hither, that I may send thee to the king, to say, Wherefore am I come from Geshur? it had been good for me to have been there still: now therefore let me see the king's face; and if there be any iniquity in me, let him kill me.

And the Gibeonites said unto him, We will have no silver nor gold of Saul, nor of his house; neither for us shalt thou kill any man in Israel. And he said, What ye shall say, that will I do for you.
