'Sword' in the Bible

So God drove the man out; and at the east of the Garden of Eden He [permanently] stationed the cherubim and the sword with the flashing blade which turned round and round [in every direction] to protect and guard the way (entrance, access) to the tree of life.

But you shall live by your sword,And serve your brother;However it shall come to pass when you break loose [from your anger and hatred],That you will tear his yoke off your neck [and you will be free of him].”

Then Laban said to Jacob, “What do you mean by deceiving me and leaving without my knowledge, and carrying off my daughters as if [they were] captives of the sword?

They killed Hamor and his son Shechem with the edge of the sword, and took Dinah out of Shechem’s house [where she was staying], and left.

Moreover, I have given you [the birthright,] one portion [Shechem, one mountain ridge] more than any of your brothers, which I took [reclaiming it] from the hand of the Amorites with my sword and with my bow.”
