to put a garment on a body: to get dressed, to wear, or to dress someone else
At its heart this word is about putting clothing onto a body. It covers the whole simple act: pulling a garment on yourself, having it on as you go about your day, and putting it on someone else. Hebrew lets one word carry both sides of that act, so the same verb means "to get dressed" and "to dress another person," with the form of the word telling you which.
Because clothing in the Bible says so much about who a person is, their rank, their mood, their state of mourning or celebration, the word reaches naturally into word-pictures. A person can be "clothed" with righteousness, with salvation, with strength, or with shame, the way a body is wrapped in a robe. The image is always the same: something settles over a person and becomes how they appear and what they are known by.
The sharpest of these pictures is when God's Spirit "clothes" a person. The Spirit comes over a man like a garment pulled on, taking hold of him for a task. The plain act of dressing and the deepest pictures of character and divine power are all the same verb, held together by one idea: what covers you shows what you are.
