ואני הנה נתתי לך, (G–d speaking to Aaron) “as far as I am concerned, lo, I have given to you charge of My heave offerings;” in this paragraph all of the 24 different kinds of gifts reserved for the priests are collectively described as תרומה, “heave offering.”

מן האש כל קרבנם, “reserved from the fire; each of their offerings.” These offerings also include baked goods, i.e. the minchah offerings.

ולכל חטאתם, “and all of their various kinds of sin offerings.”

ולכל אשמתם, “and all of their various kinds of guilt offerings.”

אשר ישיבו לי, “which they return to Me;” i.e. which are symbols of their having returned to Me in repentance. This is a specific reference for repentance for having stolen from a convert, who has died in the interval, and to whom no restitution can be made by the thief. By giving the value to the priest, it is considered as having been returned to G–d, Who is the original owner of everything.

תרומת מתנם, “the heave offering of their gift;” this is a reference to the parts of the thanksgiving offerings designated for the priests and the parts of the peace offerings of sheep and bullocks, i.e. chest, foreleg, stomach and jaw.

כל חרם, “everything that has been proscribed (for ordinary Israelites) as detailed forthwith;”

כל פטר רחם, “the first issue of every womb;” this is a reference to the firstborn male child which needs to be redeemed for five shekalim.

ואת בכור בהמה הטמאה “as well as the firstborn of the ritually unclean domestic beasts;” the only animal that fits this description among the ritually unclean beasts is the donkey/ass.

בכור שור, בכור כשב או בכור עז, “the firstborn of the oxen, sheep or goats;” these are the firstborn of the ritually pure beasts.”
