The qualifications of bail shall be as follows:
1. Each of them shall be a resident and householder, or freeholder, within the county.
2. Each shall be worth the amount specified in the order of arrest, or the amount to which the order is reduced, as provided in this chapter, over and above all debts and liabilities of the bail, exclusive of property exempt from execution; but the judge, or clerk, on justification, may allow more than two sureties to justify severally in amounts less than that expressed in the order, if the whole justification be equivalent to that of two sufficient bail.
