The people of the army are compared to sheep that have no one to lead them because their shepherd, the king, has died. (See: [[rc://en/ta/man/jit/figs-simile]])
Yahweh speaks of the king as if he were a shepherd. Just like a shepherd is responsible to care for and protect his sheep, the king is responsible to lead and protect his people. Alternate translation: "These people no longer have a leader" (See: [[rc://en/ta/man/jit/figs-metaphor]])
