2nd Aliya: Hashem (G-d) promises (25:21-22) that He will provide for the nation, regardless of the land being fallow. No one will go hungry. The return, at Yovel, of all hereditary lands to their original owners is commanded.
3rd Aliya: The difference between the sale of a property in a walled city vs. an unwalled city is established. Continuing the theme of providing and dependency, we are commanded to provide for our impoverished brethren. Just as Hashem provides for us, we must provide for each other.
4th Aliya: The freeing of all Jewish slaves at the Yovel is detailed. The Torah discusses redeeming a Jewish slave from a non-Jewish owner, and the formula for how much to pay the non-Jewish master. We begin reading Bechukotai. The opening verses describe the wondrous successes awaiting the nation, so long as they follow Hashem's Mitzvos.
5th Aliya: This Aliya is called the Tochacha – The Rebuke. It is a lengthy description of the terrible punishments awaiting the nation, if they do not follow the Torah. It is customary for the Baal Koreh (Reader) to have this Aliya, and to read it faster and more quietly than the rest of the Parasha.
6th Aliya: The established prices for endowments of individual worth, or that of an animal, are listed.
7th Aliya: The final portion deals with endowments of property to the Bet Hamikdash.
