conceived] It is an allusion to, or a metaphor taken from teeming women, who first conceive, and then bring forth. Now lust may then be said to have conceived, when the will entertaines those evill motions with consent and delight, which lust hath stirred up.
bringeth forth sinne] That is, in outward act and deed; and therefore though lust be not such a sinne, yet it may be, and is properly sinne. See Romans 7:7.
finished] Or, fully perfected. That is, committed advisedly, deliberately, or with the full consent of the will: or come to its height.
