2 Kings 7:13

And one of his servants answered and said, Let some take, I pray thee, five of the horses that remain, which are left in the city, (behold, they are as all the multitude of Israel that are left in it: behold, I say, they are even as all the multitude of the Israelites that are consumed:) and let us send and see.

Cross-reference

2 Kings 7:4 has the lepers reasoning that staying means death so they take a risk — the servant uses the same logic about the horses.

2 Kings 6:33 shows the king's despair during the siege — this servant's proposal directly responds to that hopelessness.
