'By the Sword' in the Bible

and they mourn, and weep, and fast till the evening, for Saul, and for Jonathan his son, and for the people of Jehovah, and for the house of Israel, because they have fallen by the sword.

'Wherefore hast thou despised the word of Jehovah, to do the evil thing in His eyes? Uriah the Hittite thou hast smitten by the sword, and his wife thou hast taken to thee for a wife, and him thou hast slain by the sword of the Bene-Ammon.
