The Hebrew verb azar (אָזַר) means to gird, to bind around, to encircle. It is used both literally (girding with a belt or sash) and metaphorically, especially in the powerful sense of God girding a person with strength. The metaphor evokes preparation for battle, service, or royal authority.
In Hebrew poetry, to be azur (girded) by God is to be equipped, strengthened, and prepared for one's calling. David uses this language with profound gratitude: "You armed me with strength for battle" (Psalm 18:39) — literally "You girded me with strength." God girds the warrior, the priest, and the king. Most striking is Psalm 65:6: God is described as girded with might — He is the mighty one who wears His own strength as a garment. Jesus "girded himself with a towel" (John 13:4) in a stunning reversal — the Master taking the posture of a servant, redefining what divine strength looks like.
