Leviticus 14:1–15:33
Last week's Parshah described the signs of the metzora (commonly mistranslated as "leper")—a person afflicted by a spiritual malady which places him or her in a state of ritual impurity. This week's Torah reading begins by detailing how the recovered metzora is purified by the kohen (priest) with a special procedure involving two birds, spring water in an earthen vessel, a piece of cedar wood, a scarlet thread and a bundle of hyssop.
A home can also be afflicted with tzaraat by the appearance of dark red or green patches on its walls. In a process lasting as long as nineteen days, a kohen determines if the house can be purified, or whether it must be demolished.
Ritual impurity is also engendered through a seminal or other discharge in a man, and menstruation or other discharge of blood in a woman, necessitating purification through immersion in a mikvah.
II Kings 7:3-20 (Haftorah for Shabbat HaGadol below)
This week's haftorah discusses the story of four men stricken by tzara'at, a skin ailment caused by sins — one of the main topics of this week's Torah reading.
Haftorah's backdrop: King Ben-Hadad of Aram besieged Samaria (the Northern Kingdom of Israel). The resulting famine was catastrophic, reducing many to cannibalism. King Jehoram of Israel wanted to execute the prophet Elisha, considering that his prayers could have prevented the entire tragedy. Elisha reassured the king: "So has G‑d said, 'At this time tomorrow, a seah of fine flour will sell for [merely] a shekel, and two seahs of barley will sell for a shekel in the gate of Samaria.'" One of the king's officers present scoffed at the prophecy: "Behold, if G‑d makes windows in the sky, will this thing come about?" Elisha responded, "Behold, you will see with your own eyes, but you shall not eat there from."
Now, four men suffering from tzara'at dwelled in quarantine outside the city. They too were hungry, victims of the famine. They decided to approach the enemy camp to beg for food. They arrived only to find a deserted camp. For "G‑d had caused the Aramean camp to hear the sound of chariots and the sound of horses, the sound of a great army. And they said to one another, 'Behold, the king of Israel has hired against us the kings of the Hittites and the kings of the Egyptians to attack us.'" The entire enemy army fled, leaving behind their tents, horses, donkeys and provisions.
The four men went to the city and reported their findings to the gatekeepers who, in turn, informed King Jehoram. Though originally thinking that this was an ambush planned by the enemy, the king sent messengers who confirmed the miracle. The people swarmed out of the city and looted the enemy camp, thus breaking the famine and fulfilling Elisha's prophecy.
And the officer? The king placed him in charge of the city gates. He was trampled to death by the rampaging crowds — after seeing the fulfillment of the prophet's words...
Shabbat HaGadol
The haftorah for Shabbat Hagadol is from the Book of Malachi, who lived at the beginning of the Second Temple era. He foretells of the time of Moshiach, and rebukes the Jewish people for putting the wicked on a pedestal, for not serving G‑d, especially for not tithing, and ends with a proclamation about the Redemption.
When and Why We Read This Haftorah?
Many communities, including Chabad, read this haftorah only when Shabbat Hagadol falls on Erev Pesach. Others read it on every Shabbat Hagadol, whether or not it falls on Erev Pesach.
We read this haftorah now because it speaks of giving tithes, and on Erev Pesach of the fourth and seventh years of the Sabbatical cycle, one is obligated to give whatever tithes are left in his possession. Another reason is that it tells about the future Redemption. Since Pesach is the holiday of Redemption and the most opportune time for the coming of Moshiach, we read about the Redemption before Passover, most appropriately the prophecy of Elijah the Prophet heralding Moshiach's coming
