What does Uriel mean?
Hebrew name combining 'ur' ('light, flame') with 'el' ('God'), usually translated 'God is my light' or 'flame of God'. Uriel is an archangel traditionally linked with fire; the element 'ur' carries both 'light' and 'flame' senses, so the fire reading is one of two.
What does Gideon mean?
From the Hebrew verb gada, 'to hew down, cut off,' hence 'hewer' or 'feller' — fitting the judge who cut down Baal's altar (Judges 6). The common 'mighty warrior' gloss is a secondary association from his role, not the meaning of the root; because no noun is formed from the verb, the exact nuance stays somewhat uncertain.
