[250] Which, but for him that had your husband’s ring,
Had quite miscarried: I dare be bound again,
My soul upon the forfeit, that your lord
Will never more break faith advisedly.
Por. Then you shall be his surety. Give him this,

[258] Por. I had it of him: pardon me, Bassanio;
For, by this ring, the doctor lay with me.
