Notes on the Bible, by Albert Barnes, [1834], at sacred-texts.com
This chapter would seem to take its place more naturally before Lev 12:1-8, with the subject of which it is inmediately connected. Compare especially Lev 12:2 with Lev 15:19. It stands here between two chapters, with neither of which has it any close connection.
The mere cessation of the issue does not make him clean: he must wait seven days, etc., preparatory to his offering sacrifice.
Most of the ancient religions made a similar recognition of impurity and of the need of purfication.
Every garment - Compare Jde 1:23.
This must refer to an unexpected occurrence. Intercourse during the acknowledged period was a heavy crime, and was to be punished by "cutting off" Lev 18:19; Lev 20:18; Eze 18:6.
This solemn admonition is addressed to Moses and Aaron, see Lev 15:1.
My tabernacle - Strictly, "my dwelling-place" משׁכן mı̂shkān, as in Lev 8:10; Lev 17:4; Lev 26:11. The word rendered "tabernacle" elsewhere in Leviticus is properly "tent." See the Exo 26:1 note.
