Leviticus 15:13
And when he that hath an issue is cleansed of his issue; then he shall number to himself seven days for his cleansing, and wash his clothes, and bathe his flesh in running water, and shall be clean.
And when he that hath an issue is cleansed of his issue,.... That is, it is ceased from him, as the Targum of Jonathan and Jarchi explain it; for otherwise, according to the ceremonial law, he was not yet cleansed, until he had done everything next prescribed; but when he perceived there was an entire stop put to his disorder:
then he shall number to himself seven days for his cleansing; by which time it would appear whether he was thoroughly rid of it or not; and these seven days, as Jarchi observes, must be seven pure days, quite free from pollution, and continued in a constant course, without interruption; for, as Gersom says, if he saw any impurity in anyone of these days it did not come into the account: nay, according to Maimonides {b}, he must begin to number again from the day of the last appearance:
and wash his clothes, and bathe his flesh in running water; typical of the fountain opened in Christ to wash in for sin and uncleanness, even the fountain of his blood, which cleanses from all sin; and in which both the persons and garments of the saints are washed and made white:
and shall be clean; in a ceremonial sense; as all that are washed from their sins in the blood of Christ are clean in a spiritual and evangelical sense.
