Leviticus 15:3

And this shall be his uncleanness in his issue: whether his flesh run with his issue, or his flesh be stopped from his issue, it is his uncleanness.

This shall be his uncleanness in his discharge: whether his body runs with his discharge, or his body has stopped from his discharge, it is his uncleanness.

And this shall be his uncleanness in his issue: whether his flesh run with his issue, or his flesh be stopped from his issue, it is his uncleanness.

and this is his uncleanness in his issue -- his flesh hath run with his issue, or his flesh hath stopped from his issue; it `is' his uncleanness.

This uncleanness is from his discharge, whether his body allows the discharge to flow or blocks it. So his discharge will bring about uncleanness.
