The Hebrew tashbets describes a checker-patterned weave or a mosaic setting — specifically the interlocking gold setting used to hold the twelve precious stones in the high priest's breastplate (Exodus 28:20). The term conveys intricate craftsmanship: each stone of the twelve tribes held secure in its place by skilled artistry. The word also appears for fine linen woven in a checker pattern for the priestly garments.
The tashbets setting of the high priest's breastplate carries profound theological meaning. Twelve stones — one for each tribe of Israel — held securely in interlocking gold settings, worn over Aaron's heart 'before the LORD continually' (Exodus 28:30). This is the priestly act of intercession: bearing the names of God's people close to the heart, each one secured in place, none lost. Jesus as our Great High Priest bears His people's names before the Father — none will be lost from His breastplate (John 10:28).
