The topic of this metaphor is that because of what the Spirit did, Gideon had special powers. Possible images are 1) the Spirit came over or came on or covered Gideon like a garment, thus giving Gideon special powers. Alternate translation: "came over Gideon" or "took control of Gideon" Or 2) the Spirit covered himself with Gideon and so acted through him. (See: [[rc://en/ta/man/jit/figs-metaphor]])
