Yes I can. In fact, I already have commented on these verses in this section.
Exodus 30:36 deals with the location of the Holy Incense. Namely, that it were to be placed upon the Golden Altar of Incense that stood inside the Holy Place of the Tent of the Tabernacle, like so:
Exodus 30:38 deals with the prohibition of making this incense for personal use and any other purpose than that of the priestly service. Luckily, most ingredients to make such incense cannot be identified today due to lack of research on the matter, so it is highly unlikely that it would be possible for most people to make one even if they would want to.
Perhaps the prohibition of making such incense for non-service use was due to the fact that this particular recipe had a very memorable scent qualities, and only very spiritually strong and disciplined person (such as the priest) could handle it, without getting too emotionally involved.
