Amar'e Stoudemire's Wife -- He Might Play for Israeli Team ... Might Get Bar Mitzvah

Amar'e Stoudemire could be the largest Bar Mitzvah boy to ever walk the earth ... because his wife tells TMZ Sports the NBA star is open to finally becoming a man!

We spoke to Alexis Stoudemire in NYC yesterday -- and while we initially asked about reports that her 6'11" husband would consider playing in Israel after next season (she says "maybe in the future") ... she also told us that she and Amar'e are more Jewish than we thought!

-- Do they observe Shabbat? Yep.
-- Does Amar'e fast on Yom Kippur? Sometimes.
-- Does he own a Knicks-themed yarmulke? You bet your kosher ass he does!
