שמות, פרק ל״ח, פסוק א׳

The altar for burnt offerings was constructed from acacia wood, with strict attention paid to its exact physical dimensions. The final structure measured five cubits in length and five cubits in width, forming a perfect square, and stood three cubits tall [ביאור שטיינזלץ].

The account of the altar's creation closely echoes the original instructions given for its design. While the narrative repeats the earlier command to build the structure, it does so with only slight linguistic variations, reflecting the faithful and precise execution of the original blueprint [קאסוטו].
