II Samuel 6:1-19.
This week's haftorah mentions how Uzzah was struck dead when he disrespectfully touched the Ark of the Covenant; reminiscent of Nadab and Abihu's death described in this week's Torah reading.
The Holy Ark had been in storage in the house of Avinadav for many years, ever since the destruction of the Tabernacle in Shiloh. Recently crowned King David decided to move the Ark to the new capital, Jerusalem. He had the Ark placed on a cart and it was transported amidst singing and dancing. When the procession reached Goren Nachon, the oxen misstepped and Uzzah, Avinadav's son, took hold of the Ark to steady it—whereupon he was instantly killed. David was devastated, and he temporarily placed the Ark in the home of Oved-edom the Edomite, where it remained for three months.
"And it was told to King David saying: 'G‑d has blessed the house of Oved-edom, and all that belongs to him, because of the Ark of G‑d.' And David went and brought up the ark of G‑d from the house of Oved-edom into the City of David with joy." The Ark was brought up to the city of David with great singing and dancing. David then blessed and distributed presents to all the assembled Israelites.
