What happened to all the orphans in Mitzraim?

during the holocaust loyal lenu how many orphans were they and who took care of them I don't know exactly the historical answer to that question but in mit this a similar thing happened and kish went ahead and rolled up their sleeves and said we got to take care we have to take a kid from every one of these families four fifth of kong Israel died so it comes out that there were thousands and thousands and thousands of orphans what happened to all those orphans salon suggests that claw yourself seeing all these orphans everybody has to take at least one child from all the families that died one kid from every family plus your children so when the tumison says they went out within doesn't mean there were five kids that means your own kids and kids from the four fifths of Cloud Israel that already died.
