'Curved' in the Bible

The Lord told Joshua, "Hold out toward Ai the curved sword in your hand, for I am handing the city over to you." So Joshua held out toward Ai the curved sword in his hand.

Joshua kept holding out his curved sword until Israel had annihilated all who lived in Ai.

From the top of the hill the border curved to the spring of the Waters of Nephtoah, went to the cities of Mount Ephron, and then curved to Baalah (that is, Kiriath-jearim).

Then the border reached to the slope north of Ekron, curved to Shikkeron, proceeded to Mount Baalah, went to Jabneel, and ended at the Mediterranean Sea.

On the west side, from the hill facing Beth-horon on the south, the border curved, turning southward, and ended at Kiriath-baal (that is, Kiriath-jearim), a city of the descendants of Judah. This was the west side of their border.

It curved northward and went to En-shemesh and on to Geliloth, which is opposite the Ascent of Adummim, and continued down to the Stone of Bohan son of Reuben.
