3 Whether it continues flowing from his body or is blocked, it will make him unclean. This is how his discharge will bring about uncleanness:

Read Leviticus 15:3 Using Other Translations

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 the law of his uncleanness for a discharge: whether his body runs with his discharge, or his body is blocked up by his discharge, it is his uncleanness.
This defilement is caused by his discharge, whether the discharge continues or stops. In either case the man is unclean.
