What does Tobias mean?
From the Hebrew Toviyya, “God is good.”
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.
