The 143rd prohibition is that we are forbidden from consuming oil which is ma'aser sheni outside Jerusalem.
The source of this prohibition is G‑d's statement,1 "In your own settlements, you may not eat the tithes of your grain, wine, and oil."
One who doesn't redeem it and eats it [outside Jerusalem] is punished by lashes, subject to the same condition mentioned regarding ma'aser sheni of grain.2
Perhaps you are surprised that we counted ma'aser sheni of grain, ma'aser sheni of wine, and ma'aser sheni of oil as three separate mitzvos. However, you must be aware that one who ate all three of them receives a separate set of lashes for each.3 This is not an "inclusive prohibition" [lav she'b'klallus] for which [more than one set of4] lashes is not given.5 Rather, the verse is written in this way to divide them [to count as separate mitzvos].
This is stated explicitly in tractate Krisus:6 "One who consumes grain, wine, and oil of ma'aser [sheni] receives lashes for each one. But is one lashed separately for [the components of] a lav she'b'klalus?! But this case is different because there is a redundant verse: It is written,7 'You shall consume the ma'aser [sheni] of your grain, wine, and oil before G‑d your L‑rd...' Why did the Torah need to repeat them all?8 From this we see that the Torah divided them [into separate mitzvos]. And our Sages said in Makos:9 "It is written, 'You shall consume the ma'aser [sheni] of your grain, wine, and oil before G‑d your L‑rd...' But the Torah could have just written, 'You may not eat them in your own settlements'! Why did it list each one separately? To designate each one as a separate prohibition." This demonstrates that everything listed in the verse counts as a separate mitzvah.
I will now list the other prohibitions included in this verse.10
