Leviticus 15:2

2. Issue out of his flesh The word flesh is here a euphemism for the part on which circumcision was performed. “My covenant shall be in your flesh.” Genesis 17:13. The Targum of Palestine adds, “When the man hath seen the defluxion three times, he is unclean.” The Seventy have translated the “issue” by gonorrhea. Keil questions the existence of this disease in its syphilitic character at so early a period, and inclines to the theory of an involuntary flow, drop by drop, through weakness, and he suggests that its more appropriate name is blenorrhea urethrae, a catarrhal affection of the mucus membrane of the urethra.
