He he.
(1) Jesus is a moderately common name in the 1st century, especially in the Jerusalem Sadducean circles, most probably referring to the high priest of the restoration (this one being an "anointed", a "Christos Ièsous") ; perhaps in Galilee too, then referring to Joshua ben Nun (Ièsous huios Nauè) as Moses' successor which is to fulfill the promises to Moses (JbN is from the northern tribe of Ephraim), as a warlike Messiah.
(2) There is little evidence for actual "Jesus worship" based on either character, but both were clearly full of "messianic" expectations. This name was clearly thought of as "meaningful," including in the Greek realm:
- in Numbers 13:16 Joshua-Ièsous is especially given to Hoshea ben Nun as a "new name";
- in Siracides 46:1 (the author being Jesus ben Sirach) we read: "Joshua (Ièsous) son of Nun was mighty in war, and was the successor of Moses in the prophetic office. He became, as his name implies, a great savior of God's elect, to take vengeance on the enemies that rose against them, so that he might give Israel its inheritance.
- Matthew who always quotes the LXX has no need for translation to write (in Greek!, 1:21): "She will bear a son, and you are to name him Jesus, for he will save (sôsei) his people from their sins.
- The Synoptic apocalypses have political would-be Messiahs coming in his name (Mark 13:6//).
- Last but not least, "Jesus" works as a "coronation name" in Philippians 2: " Therefore God also highly exalted him and gave him the name that is above every name, so that at the name of Jesus every knee should bend, in heaven and on earth and under the earth..."
Back to Gumby's question, as Pete said there are many historical characters echoed in the Jesus stories. Some we know about by other sources (such as Jesus ben Ananias who foretold the ruin of the temple and city according to Josephus), others (named Jesus or something else) we'll never know about. However those stories also seem secondary to the Christian myth of Christos Ièsous as a heavenly savior. The ultimate question is, did the specifically Christian myth bead need a historical Jesus grain of sand to form in the first place? Perhaps; not that it is so important when you put the question in perspective...
