#2 Sorry, the gold was not "stolen." The Jews asked for the gold and the Egyptians handed it over...willingly. (Well, maybe after some strong arm tactics by GOD LOL)
35 (1) Now the sons of Israel had done according to the word of Moses, for they had requested from the Egyptians articles of silver and articles of gold, and clothing;
36 and the LORD had given the people favor in the sight of the Egyptians, so that they let them have their request. Thus they (2) plundered the Egyptians
If the egyptians persue this, at somepoint they are going to have to admit to the whole world that their ancestors weren't very sharp or indeed there is a God in Isreal.
