The Hebrew word karkôb, represented by H3749, is a specific architectural term defined as a rim or top margin; compass. It is a rare word in scripture, appearing only 2 times in 2 unique verses. Its meaning is confined to the structural details of the tabernacle's altar.
Both occurrences of H3749 are found in the book of Exodus, within the detailed instructions for constructing the altar of burnt offering. In Exodus 27:5, instructions are given to place a net under the compass of the altar, so that the net reaches the middle of the structure. Later, in Exodus 38:4, the fulfillment of this command is recorded, stating that a brasen grate of network was made under the compass of the altar, positioned beneath it and extending to its midpoint. The term exclusively describes a specific rim or ledge on the altar designed to hold this grate.
Several related words clarify the function and context of H3749:
- H4196 mizbêach (an altar): This is the central object to which the karkôb is attached. The altar was a primary site for worship and sacrifice, as established by figures like Abram Genesis 12:7 and designated as the place for making atonement Leviticus 17:11.
- H7568 resheth (a net; net-work): This is the object that the karkôb is designed to support. In the context of the altar, it refers to a specific grate-like structure, as described in both Exodus 27:5 and Exodus 38:4.
- H4345 makbêr (a grate): This word is used in conjunction with "network" to describe the "brazen grate" Exodus 38:4 that was made for the altar. The karkôb served as the support for this essential component.
While H3749 is a technical term, its use has theological implications related to the object it describes.
- Precision in Holy Objects: The existence of such a specific term for a single part of the altar highlights the meticulous detail God required for the construction of the tabernacle. It reflects a divine blueprint where every component has a designated place and purpose (Exodus 27:5, Exodus 38:4).
- Supporting the Place of Atonement: The karkôb's function was to hold the grate of the altar H4196, the very place where sacrifices were offered. In doing so, it played a critical, supportive role in the system of atonement God established for Israel Leviticus 17:11.
- A Symbol of Order: As a "rim or top margin," the word implies structure, boundary, and order. This speaks to the set-apart nature of the holy furnishings and the prescribed order for approaching a holy God.
In summary, H3749 karkôb is not a word with broad application but a precise term for a rim or ledge on the tabernacle's altar. Its significance is derived entirely from its context as a component of this crucial instrument of worship. The use of such a specific word demonstrates the profound importance of detail, order, and obedience in the construction and function of objects dedicated to God.
