'Sword' in the Bible

So he sent the man out; and at the east of the garden of Eden he put winged ones and a flaming sword turning every way to keep the way to the tree of life.

By your sword will you get your living and you will be your brother's servant; but when your power is increased his yoke will be broken from off your neck.

And Hamor and his son they put to death with the sword, and they took Dinah from Shechem's house and went away.

And I have given you more than your brothers, even Shechem as your heritage, which I took from the Amorites with my sword and my bow.
