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 Reuben mean?
Hebrew Re'uven, literally 'behold, a son!' (re'u 'see, behold' + ben 'son'). Genesis 29:32 layers a second biblical wordplay on it: Leah says 'the LORD has looked upon (ra'ah) my affliction' — that play is theological rather than the strict etymology.
