A Reliable Guarantor
"I desperately need a loan for a half year," said the newcomer to Yeshaya Jochovitzer. "Since I am new here I cannot provide any guarantor. Only G-d knows that I am an honest person and He can be my guarantor."
"There is no better guarantor," said Yeshaya as he extended the requested loan.
Half a year later the borrower smilingly returned to repay the loan, adding that the money had helped him to succeed in his business. But Yeshaya refused to accept the money, explaining that the Divine Guarantor had already repaid the loan by blessing him with an unexpected profit in the exact amount of the loan.
