A sword is a weapon that has a long sharp blade and a handle at one end. People hold the handle and hit or stab the enemy with the sharp blade. If your people don’t have a weapon just like this, you could translate it as: “A long knife” or “A machete” or “A bush knife.”
Here **sword** is a metonym that refers to their fighting. Alternate translation: “We fight for Yahweh and for Gideon” (See: [[rc://en/ta/man/translate/figs-metonymy]])
This is a strong statement that Gideon was depending on Yahweh, and not the sword, for his victory. (See: [[rc://en/ta/man/translate/figs-exclamations]])
