'Sheathed' in the Bible

When they were at the great stone in Gibeon, Amasa came to meet them. Now Joab was wearing his military uniform, and over it he had a belt with a sheathed sword strapped around his hips; and as he went forward, it fell out.

and all living will know [without any doubt] that I the Lord have drawn My sword out of its sheath; it will not be sheathed again.”’
