Commentary for Kiddushin 96:2

In respect to this we have two views: one view is that the artisan acquires title to the increase in the value of the material upon which he works as a result of the improvements he effects, and when he gives it back, he is really selling it for the agreed cost of his labour. Hence, the woman is betrothed, since she receives something for which she would have to pay now. The other view is that he does not so acquire; consequently, his wages are a liability and debt, just as those of a time worker; and so she is not betrothed.');"><sup>2</sup></span> Alternatively, all hold that an artisan does not obtain a title to the improvement of the utensil, and that wages are a liability from beginning to end, and that betrothal with debt is not valid, but the circumstances here are that he added a particle [of metal] of his own: one Master holds, [When one betroths a woman with a] debt and a perutah, her mind is set upon the perutah;<span class="x" onmousemove="('comment',' His labour is a debt, whilst his own additional material is certainly like a coin given now.
