'Kill' in the Bible

And Absalom 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 thy handmaid, and they say, Deliver him that smote his brother, that we may kill him for the life of his brother whom he slew, and so destroy the heir also. Thus will they quench my coal which is left, and will leave to my husband neither name nor remainder upon the face of 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 were better for me to be there still. Now therefore let me see the king's face; and if there be iniquity in me, let him kill me.
