'Sword' in the Bible

After he had expelled the man, the LORD God placed winged angels at the eastern end of the garden of Eden, along with a fiery, turning sword, to prevent access to the tree of life.

By your sword you'll live; but you'll serve your brother. But when you've become restless, you'll break off his yoke from your neck."

Three days later, while they were still in pain, Jacob's sons Simeon and Levi, two of Dinah's brothers, each grabbed a sword and entered the city unannounced, intending to kill all the males.
