According to Sefer Ha-Chinuch, there are four positive and five negative commandments in the parsha.
To give a half shekel annually
A Kohen must wash his hands and feet before service
To prepare the anointing oil
Not to anoint a stranger with anointing oil
Not to reproduce the anointing of
Not to reproduce the incense formula
Not to eat or drink anything from an offering to an idol
To let the land lie fallow in the Sabbatical year
Not to cook meat and milk together
Rambam, however, attributed to this parsha only the following four positive and three negative commandments.
To give a half shekel annually
A Kohen must wash his hands and feet before service
To prepare the anointing oil
Not to reproduce the anointing oil
Not to anoint a stranger with anointing oil
Not to reproduce the incense formula
To let the land lie fallow in the Sabbatical year
