The abnet was the priestly sash or girdle that encircled the waist of the High Priest and ordinary priests. It was a woven garment of fine linen with blue, purple, and scarlet threads.
In the Old Testament, the abnet was not merely functional — it was a garment of holiness, crafted according to God's precise specifications (Exodus 28:39). The girded priest was one prepared for service. In the New Testament, Paul picks up this imagery in the "belt of truth" (Ephesians 6:14), where truth — the first piece of spiritual armor — encircles the believer. Readiness for service before God is always pictured as a girded servant.
