 We or our bailiffs will not seize for any debt, any land or rent, so long as the available shuttles of the debtor are sufficient to repay the debt, and the debtor himself is prepared to have it paid therefrom, nor will those who have gone surety for the debtor be restrained so long as the principal debtor is himself able to pay the debt. And if the principal debtor fails to pay the debtor having nothing wherewith to pay it or is able but unwilling to pay, then shall the surety's answer for the debt and they shall, if they wish, have the lands and rent of the debtor until they are reimbursed for the debt which they have paid for him, unless the principal debtor can show that he has discharged his obligation in the matter to the said surety's.
