Leviticus 15 speaks of intimate matters, showing the Israelites, and then the entire world, that all things pertaining to man concern God.

Verses 1–12 deal with male discharges without specifying what the discharge might be (Obviously, something other than the normal daily waste that our bodies discharge), but those discharges made an Israelite male unclean, and once he had gone through the process of cleansing, he had to count seven days,

“And when he who has a discharge is cleansed of his discharge, then he shall count for himself seven days for his cleansing, wash his clothes, and bathe his body in running water; then he shall be clean” (Leviticus 15.13).

Once he had gone through this seven day period, he was cleansed, that is, perfectly or completely cleansed.
