sword

dagger, swordsmen

Definition:

A sword is a flat-bladed metal weapon used to cut or stab. It has a handle and a long, pointed blade with a very sharp cutting edge.

In ancient times the length of a sword’s blade was about 60 to 91 centimeters.
Some swords have two sharp edges and are called "double-edged" or "two-edged" swords.
Jesus' disciples had swords for self defense. With his sword, Peter cut off the ear of the high priest's servant.
Both John the Baptist and the apostle James were beheaded with swords.
A "dagger" is a short sword used to stab people who are close by.

A sword is used as a metaphor for God's word. God's teachings in the Bible exposed people's innermost thoughts and convicted them of their sin. In a similar way, a sword cuts deeply, causing pain. (See: rc://en/ta/man/jit/figs-metaphor)
One way to translate this figurative use would be, "God's word is like a sword, which cuts deeply and exposes sin."
Another figurative use of this term occurred in the book of Psalms, where the tongue or speech of a person was compared to a sword, which can injure people. This could be translated as "the tongue is like a sword that can badly injure someone."
If swords are not known in your culture, this word could be translated with the name of another long-bladed weapon that is used to cut or stab.
A sword could also be described as a "sharp weapon" or "long knife." Some translations could include a picture of a sword.
