שמות, פרק ל״ט, פסוק י״ג

Crafting the final row of precious stones for the breastplate required a high level of skill to ensure the gems remained perfectly secure. Each individual stone was carefully placed into a dedicated gold frame designed to hold it firmly within its specific row [ביאור שטיינזלץ].

The construction involved a distinct element of practical creativity. The original command to build the breastplate did not specifically require the craftsmen to enclose the gems from all sides. A simple top setting resting on a gold base would have been enough to meet the requirement. However, Bezalel applied extra wisdom to the task. He fashioned small clasps, or teeth, that gripped the bottom of each stone as well. Because of this added detail, the gold frame completely surrounded and secured the gems much more tightly than initially demanded [העמק דבר].
