DaasYochid and Littlr Froggie:mu apologies for questioning your status and motives.
MDG: You are mistaken. The targum that you quote is NOT Yonatan bn Uziel. It is a targum of much later date, probably fourth or fifth century. It does mention the Bnai Efraim on that possuk but what does this have to do with sholosh shevuos? Check the text and you will see that it had to do with golus mitzrayim not with any contemporary situation.
