Adornment, glory, splendor, beauty — the visible majesty that accompanies God's presence and the honor due to Him. Related to hadar (H1926, splendor), this word captures the aesthetic dimension of holiness.
Hadarah teaches that holiness is not drab — it is dazzling. 'Worship the LORD in the beauty of holiness' (Ps 29:2) reveals that true worship engages beauty as a window into God's nature. The tabernacle's elaborate design, the priestly garments 'for glory and for beauty' (Ex 28:2), and the visions of heaven in Revelation all confirm that God's holiness radiates aesthetic splendor.
