Caldron
The caldron is a large boiling-vessel of the Israelite worship system — one of the bronze pots in which sacrificial flesh and holy offerings were cooked at the sanctuary. It appears in the narrative books at three sanctuary settings (Shiloh, the Josianic temple, and the Babylonian deportation), and once as Ezekiel's prophetic figure for besieged Jerusalem.
At the Shiloh Sanctuary
The caldron first appears in the indictment of Eli's sons. Their attendant struck the boil-vessels with a three-tooth flesh-hook to seize the priest's portion before the offering had been properly burned: "and he struck it into the pan, or kettle, or cauldron, or pot; all that the flesh-hook brought up the priest took with it. So they did in Shiloh to all the Israelites who came there" (1Sa 2:14). The caldron sits third in a four-vessel sequence — pan, kettle, cauldron, pot — with the strike-verb taking the whole list as alternative objects. The verse exhibits the caldron as one of the ordinary Shiloh boil-vessels from which the priestly grab-ritual extracted pre-burnt sacrificial flesh.
At Josiah's Passover
In the Josianic temple the caldron is named again, this time as part of a prescribed three-vessel cook-set for the holy offerings that accompanied the paschal lamb. Roasting and boiling are deliberately separated: "they roasted the Passover with fire according to the ordinance: and the holy offerings they boiled in pots, and in caldrons, and in pans, and carried them quickly to all the sons of the people" (2Ch 35:13). The Passover-lamb itself follows the Exodus-12 fire-roasting; the remaining sacred portions are routed into a distinct boil-track. Within that boil-track caldrons stand in the middle slot of the pots / caldrons / pans triplet, and the cook-cycle closes with a rapid distribution to the assembled people.
Carried Away to Babylon
When Nebuzaradan strips the temple, the bronze service-vessels — caldrons among them — are itemized in two parallel inventories. The first names the operative-utensil class: "the pots also, and the shovels, and the snuffers, and the basins, and the spoons, and all the vessels of bronze with which they ministered, they took away" (Jer 52:18). The second names the gold and silver pieces alongside: "and the cups, and the firepans, and the basins, and the pots, and the lampstands, and the spoons, and the bowls — that which was of gold, in gold, and that which was of silver, in silver — the captain of the guard took away" (Jer 52:19). The same bronze pots that boiled the holy offerings at Josiah's Passover are now carried out of the burning house as imperial spoil.
Jerusalem as the Cauldron
Ezekiel turns the cooking-pot into a prophetic figure for the besieged city. The men of Jerusalem are quoted in their own slogan — "[The time] is not near to build houses: this [city] is the cauldron, and we are the flesh" (Eze 11:3) — confident that the city's walls will hold the inhabitants the way a pot holds its meat. Yahweh inverts the figure. The slain inside the city, not the survivors, are the flesh: "Your⁺ slain whom you⁺ have laid in the midst of it, they are the flesh, and this [city] is the cauldron; but you⁺ will be brought forth out of the midst of it" (Eze 11:7). Far from sheltering its inhabitants, the cauldron empties: "I will bring you⁺ forth out of the midst of it, and deliver you⁺ into the hands of strangers, and will execute judgments among you⁺" (Eze 11:9). The closing reversal cancels the slogan outright — "this [city] will not be your⁺ cauldron, neither will you⁺ be the flesh in the midst of it; I will judge you⁺ in the border of Israel" (Eze 11:11). The cooking-pot of Jerusalem will not contain its own people; they will be taken out of it for judgment at the frontier.
