Midrasz do Kapłańska 19:22

7) (Vayikra 19:22) ("And the Cohein shall make atonement for him with the ram of the guilt-offering before the L–rd because of his sin which he has sinned, and it shall be forgiven him (of) his sin which he has sinned.") "And the Cohein shall make atonement for him with the ram of the guilt-offering before the L–rd because of his sin which he has sinned": We are hereby taught that he brings one offering for numerous acts of coitus (within the same time period). "and it shall be forgiven him (of) his sin which he has sinned": (What is the intent of this repetition?) To equate a deliberate sin with an inadvertent one (for purposes of bringing an offering).

8) (In the instance of) all the arayoth, a minor (i.e., a male of nine years of age and a female of three years of age) is equated with an adult (in making the adult partner liable for the death penalty); but with a maidservant, a minor maidservant is not equated with an adult (maidservant in making her partner liable for the death penalty [viz. Vayikra 5:2]).

9) (In the instance of) all the arayoth, peripheral intercourse is equated with consummated intercourse (vis-à-vis) the death penalty; but with a maidservant peripheral intercourse is not equated with consummated intercourse [viz. Vayikra 5:2]).
