'Swords' in the Bible

Now there was no smith found throughout all the land of Israel: for the Philistines said, Lest the Hebrews make them swords or spears:

On the day of battle, none of the people who were with Saul and Jonathan were armed with swords or spears, but Saul and his son Jonathan did have them.

Then Saul and all the people who were with him assembled and went into battle. Now the swords of all the Philistines were against each other, and there was very great confusion.

He captured alive Agag king of Amalek, but he completely destroyed all the people, executing them with swords.

He said to his men, “All of you, put on your swords!” So David and all his men put on their swords. About 400 men followed David while 200 stayed with the supplies.
