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.
What does Zebadiah mean?
From Hebrew Zebadyah, from zabad 'to give/bestow' (noun zebed 'gift') + yah (Yahweh) — 'Yahweh has bestowed/given'. A 'gift of God' name; sometimes rendered 'gift of the Lord'.
