(19) And in the place of the boil.--If the cicatriced sore breaks out again, and exhibits the usual symptoms of leprosy, the patient is to show himself to the priest.

White, and somewhat reddish.--Better, of a white-reddish colour. This symptom is peculiar to re-opened cicatriced sores, and hence has not been mentioned before. The authorities in the time of Christ describe the mixture of red and white as follows :--"It has the appearance of red wine poured into water, and is either a palish white or somewhat darker."

13:18-44 The priest is told what judgment to make, if there were any appearance of a leprosy in old sores; and such is the danger of those who having escaped the pollutions of the world are again entangled therein. Or, in a burn by accident, ver. 24. The burning of strife and contention often occasions the rising and breaking out of that corruption, which proves that men are unclean. Human life lies exposed to many grievances. With what troops of diseases are we beset on every side; and thy all entered by sin! If the constitution be healthy, and the body lively and easy, we are bound to glorify God with our bodies. Particular note was taken of the leprosy, if in the head. If the leprosy of sin has seized the head; if the judgment be corrupted, and wicked principles, which support wicked practices, are embraced, it is utter uncleanness, from which few are cleansed. Soundness in the faith keeps leprosy from the head.And in the place of the boil there be a white rising,.... In the place where the boil was, a white swelling appears:

or a bright spot, white, and somewhat reddish; white and red mixed, as the Targum of Jonathan; and so Aben Ezra interprets the word "reddish", of the bright spot being mixed of two colours, or part of it so; and such a mixed colour of white and red, Gersom observes, is usual in a swelling, and adds, we are taught how to judge of these appearances, according to a tradition from Moses, which is this: take a cup full of milk, and put in it two drops of blood, and the colour of it will be as the colour of the bright spot, white and reddish; and if you put into it four drops, its colour will be as the colour of the rising (or swelling) reddish; and if you put into it eight drops, its colour will be as the colour of the scab of the bright spot, more reddish; and if you put into it sixteen drops, its colour will be as the colour of the scab of the swelling, very red: hence it appears, says he, that the bright spot is whitest with its redness, and after that the swelling, and next the scab of the bright spot, and then the scab of the swelling; but Bochart (p) is of opinion that the word is wrongly rendered "reddish", which, he thinks, contradicts the account of the bright spot being white, and especially as the word for "reddish" has its radicals doubled, which always increase the signification; and therefore if the word bears the sense of redness, it should be rendered "exceeding red", which would be quite contrary to the spot being white at all; wherefore from the use of the word in the Arabic language, which signifies white, bright, and glittering; See Gill on Lamentations 4:7; he chooses to read the words, "or a bright spot, white and exceeding glittering": but this word we render reddish and white, being read disjunctively, Leviticus 13:24; seems to contradict this observation of his:

and it be shewed to the priest; to look upon and pass his judgment on it.
