What does "lesser" mean?

Lesser: Note: Lesser is used for less, now the compar. of little, in certain special instances in which its employment has become established by custom; as, Lesser Asia (i. e., Asia Minor), the lesser light, and some others; also in poetry, for the sake of the meter, and in prose where its use renders the passage more euphonious. The more my prayer, the lesser is my grace. Shak. The larger here, and there the lesser lambs. Pope. By the same reason may a man, in the state of nature, punish the lesser breaches of the law. Locke.
