A dramatic shift from a deadly siege and severe famine to sudden plenty occurs in the blink of an eye, proving that God's salvation can arrive rapidly and completely transform a dire reality. The people pour out of the besieged city and loot the abandoned Aramean camp, gathering the vast amounts of food left behind in the military tents. Because the enemy camp was massive and Samaria was a relatively small city, this sudden flood of food causes an immediate and steep drop in market prices [ביאור שטיינזלץ]. The cost of grain plummets from one hundred shekels down to a single shekel [צאינה וראינה].
This drastic economic shift happens exactly as God had spoken and is not a mere coincidence [מדוד ועד לחורבן]. The prophet had never promised a supernatural event where grain would rain down from the sky. Instead, the promise was simply that the prices in Samaria would stabilize and match the normal cost of grain throughout the rest of the land of Israel. Fulfilling this did not require a heavenly miracle; it only required the sudden departure of the enemy forces [מלבי״ם].
The realization of these lowered prices is directly tied to the fate of the king's officer. The king had stationed this officer at the city gate to stop the masses from taking the spoils for themselves, intending instead to claim the wealth for the royal treasury. Had the officer survived, he would have taxed the grain and artificially raised the market price, thereby preventing the prophecy of cheap food from coming true. Consequently, the desperate crowd storming the gate tramples him to death. This serves as a fitting punishment for his earlier actions. Because he disrespected the prophet, denied the abilities of God, and mocked the promise of abundance by asking if God would make windows in heaven, he is condemned to see the plummeting prices with his own eyes without ever getting to eat from the newfound bounty [מלבי״ם, צאינה וראינה].
This historical event of sudden rescue took place on the night of the first Passover. In memory of this timing, the reading of this story was established as the traditional portion for the Sabbath right before Passover, known as Shabbat HaGadol [צאינה וראינה].
