Frequently Asked Questions
Q: What is the 'grate of network of brass' mentioned in Exodus 27:4?
A: The 'grate of network of brass' (מִכְבָּר מַעֲשֵׂה רֶשֶׁת נְחֹשֶׁת) was a copper mesh grate that was part of the outer altar (מִזְבֵּחַ) in the Tabernacle. According to Rashi, it was placed halfway up the altar to hold the wood and sacrifices, allowing ashes to fall beneath it.
Q: Why were there four copper rings on the corners of the grate?
A: The four copper rings (אַרְבַּע טַבְּעֹת נְחֹשֶׁת) were attached to the grate to hold the poles used for carrying the altar, as explained in the Talmud (Zevachim 59b). This allowed the altar to be transported during the Israelites' travels in the wilderness.
Q: What is the significance of using copper in the altar's construction?
A: Copper (נְחֹשֶׁת) was used because it withstands high heat, making it practical for the altar's sacrificial fires. The Midrash (Shemot Rabbah 34:2) also teaches that copper symbolizes judgment, reflecting the altar's role in atonement and divine service.
Q: How does this verse connect to the broader purpose of the Tabernacle?
A: This detail highlights the precision required in building the Tabernacle (מִשְׁכָּן), as every component had spiritual significance. The Rambam (Hilchot Beit HaBechirah 2:1) explains that the altar's design reflects order and reverence in serving Hashem.
Q: Can we derive any practical lessons from this verse today?
A: Yes! Just as the grate supported the altar's function, we learn the importance of creating structures (physical or spiritual) that uphold our sacred duties. The Mishnah (Avot 1:2) teaches that the world stands on Torah, service (like the altar), and acts of kindness—all requiring a strong foundation.
The Copper Grate (מִכְבָּר) in the Altar
The verse describes the construction of a copper grate (מִכְבָּר) for the Mizbeach (Altar) in the Mishkan. Rashi (Exodus 27:4) explains that this grate was placed midway in the Altar's height, serving as a platform where the wood and sacrifices were placed. The Netziv (Ha'amek Davar) adds that the grate's network design allowed ashes to fall through, ensuring proper airflow for the fire.
Symbolism of the Four Copper Rings
The four copper rings attached to the grate's corners held deep significance. The Midrash (Tanchuma, Tzav 14) teaches that these rings corresponded to the four corners of the world, symbolizing that the Altar's service atoned for all humanity. Rambam (Moreh Nevuchim 3:45) suggests the copper material represented strength and durability, reflecting the enduring nature of divine service.

Kabbalistic Interpretation
The Zohar (Terumah 150a) connects the copper grate to the divine attribute of Gevurah (strength/judgment), with the network pattern symbolizing how strict judgment is filtered through mercy. The Arizal (Shaar Hakavanot) teaches that the four rings channeled divine energy to the four spiritual worlds (Atzilut, Beriah, Yetzirah, Asiyah).
