DEUT684 The more the Creator bestows favor upon a person, the greater is his obligation of service. This is illustrated by the following: Produce is subject to the law of tithing, as it says, “You shall tithe all the produce of your seed” (Devarim 14:22). One to whom God has given one hundred measures of produce is obliged to give ten measures; one to whom God has given only ten measures has to give one measure. If the former were to separate nine and a half measures and the latter were to separate one measure, the former would be punished, while the latter would receive a reward. Similarly, if someone does not have a son, the obligation of circumcising his son and teaching him Torah does not apply to him. If a person is lame, the duty of going to Yerushalayim for the three festivals is not obligatory for him. If someone is sick, those commandments which he is unable to fulfill are not binding upon him. (Continued at [[GEN1370]] Genesis 32:11 unworthy DUTIES 311).
