Isn't there a written Jewish 'confession'?
Exodus: And the children of Israel did according to the word of Moses; and they asked of the Egyptians jewels of silver, and jewels of gold, and raiment.
Seems most reasonable...they hadn't been paid for their labours for hundreds of years...IMO what is behind this action is an attempt by the arabs to blackmail the Jews into using the defense argument that the Exodus never happened, that scripture is not trustworthy...something they know they might reasonably expect of secular left-wing Jews. That then, sets precedent against Israel's claim to Jerusalem and the 'promised land'. Remember, the arab mind is utterly, totally, DEVIOUS!
