'Knife' in the Bible

And Abraham took the wood of the burnt-offering, and laid it upon Isaac his son. And he took in his hand the fire and the knife. And they went both of them together.

And Abraham stretched forth his hand, and took the knife to slay his son.

And when he was come into his house, he took a knife, and laid hold on his concubine, and divided her, limb by limb, into twelve pieces, and sent her throughout all the borders of Israel.

And put a knife to thy throat, If thou be a man given to appetite.
