Although he pays him, he is not forgiven for it until he seeks [forgiveness] from him, as it is said (Genesis 20:7): But now, return the wife ...  Now, from where do we know that the one who forgives should not be cruel? It is said (ibid., v. 17): And Abraham prayed to God, and God healed Abimelech ...  [If] one says: “Blind my eye,” “Cut off my hand,” [or] “Break my leg,” he is liable. “On condition to be exempt?” —- he is liable. “Tear my clothes,” [or] “Break my jug” —- he is liable. “On condi-tion to be exempt?” —- he is exempt. “Do this to So-and-so on condition that you be exempt” —- he is liable, whether it is against his body or against his property.

[If] one steals wood and makes it into utensils; [or] wool, and makes it into garments —- he pays as of the time of the robbery.  [If] one steals a pregnant cow, and it calves; [or] a ewe bearing wool, and he shears it —- he pays the value of the cow ready to calve [or] the value of a ewe ready to be shorn.  [If] one steals a cow, and it becomes impregnated while with him, and it calves; [or] a ewe, and it becomes laden with wool while with him, and he shears it —- he pays as of the time of the robbery.  This is the general rule: All robbers pay as of the time of the robbery.

[If] one steals an animal, and it ages; [or] slaves, and they age —- he pays as of the time of the robbery. R' Meir says: In the case of slaves he may say to him: “Here is your property before you.”  [If] he steals a coin, and it cracks; fruit, and it rots; [or] wine, and it sours —- he pays as of the time of the robbery.  [If he steals] a coin, and it becomes disqualified; terumah, and it becomes ritually contaminated; chametz, and it is in his possession on Pesach; [or] an animal, and it is used for transgression, or becomes disqualified for the Altar, or is condemned to be stoned —- he may say to him: “Here is your property before you.''

[If] one gives craftsmen [something] to improve, and they spoil [it], they are obligated to pay. [If] one gives a carpenter a chest, a box, or a closet to repair, and he spoils [it], he is obligated to pay.  [If] a builder undertakes to demolish a wall, and he breaks the stones or causes damage, he is obligated to pay. [If] he was demolishing from one side and it fell from another side, he is exempt; but if it was because of the blow, he is liable.
