שמות, פרק מ׳, פסוק ז׳

As the arrangement of the sacred vessels continues, careful attention is given to the precise location of the washbasin within the holy space. The instruction to position the basin is given even before the command to set up the Tabernacle courtyard. This specific order highlights that the basin is not merely a courtyard fixture, but an essential accessory to the altar, vital for the upcoming service [העמק דבר].

The designated spot for the washbasin is between the Tent of Meeting and the altar, a location that had been established earlier [קאסוטו]. However, this placement creates a practical challenge. The altar was set directly in front of the entrance to the Tent. If the altar stood right at the doorway, placing a washbasin directly between them would block the path. Therefore, the basin was placed in the general space between the altar and the Tent, but not in a straight line that would obstruct the entrance. Instead, it was shifted slightly toward the south. It could not be moved to the north, as that entire northern area had to remain completely clear of any vessels to allow room for the sacrificial service [תורה תמימה].

Once positioned, water was poured directly into the basin. This was done immediately, ensuring that everything was fully prepared and waiting for the sacred work to begin [ביאור שטיינזלץ].
