Moyshe couldn’t sleep one night. He was tossing and turning for hours. When his wife couldn’t take any more she asked him for an explanation. He told her that he owes Dovid from across the road 10.000$. He is supposed to pay it back the next day and he hasn’t got the money.
His wife got out of bed, opened up the window and screamed:”DOVID, DOVID!!” out the window, until the light in Dovid’s house lit up. She told Dovid that her husband doesn’t have the money which he owes him.
She returned to her bed and told her husband:” It’s all right you can go to sleep now. It is Dovid who won’t be able to sleep instead.
