At that time the Lord said to Joshua, “Make for yourself flint knives and circumcise again the sons of Israel the second time.”

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

There is a kind of man whose teeth are like swords
And his jaw teeth like knives,
To devour the afflicted from the earth
And the needy from among men.

For before the harvest, as soon as the bud blossoms
And the flower becomes a ripening grape,
Then He will cut off the sprigs with pruning knives
And remove and cut away the spreading branches.
