Deuteronomy 32:5

Deu. 32:5. "Their spot," etc. In all probability here is a reference had to those spots mentioned in Lev. 13, where are rules for the trials of spots, whether they were leprous spots or no. There are many spots there mentioned that something resembled the leprosy, notwithstanding which the diseased person was to be pronounced clean, and might still be looked upon as of the congregation of Israel, and allowed the privileges of such. But if the spot was upon trial found to be a leprosy, he was to be separated from the congregation, - his spot was not the spot of God's people, and he was not to be looked upon as one of them.
