'Knives' in the Bible

At that time the Lord said to Joshua, “Make for yourself flint knives and circumcise the [new generation of the] sons of Israel as [was done] before.”

So Joshua made flint knives and circumcised the sons of Israel at Gibeath-haaraloth.

Each one of them seized his opponent by the head and thrust his sword into his opponents side; so they fell down together. Therefore that place was called Helkath-hazzurim [that is, the Field of Sides], which is in Gibeon.

So they cried out with a loud voice [to get Baal’s attention] and cut themselves with swords and lances in accordance with their custom, until the blood flowed out on them.

There is a generation (class of people) whose teeth are like swordsAnd whose jaw teeth are like knives,To devour the afflicted from the earthAnd the needy from among men.
