Nachalah vs. Morasha

Question

On a biblical level, what is the difference (if any) between נחלה and מורשה?

We find both שרשים being used in various forms, for example:

(Deut. 32:8-9) בהנחל עליון גוים...יעקב חבל נחלתו.

(Deut. 33:4) תורה צוה לנו משה מורשה קהלת יעקב.

(Deut. 11:8) וירשתם את הארץ אשר אתם עברים שמה לרשתה.

And sometimes both words appear in the same פסוק:

(Numbers 36:8) וכל בת ירשת נחלה.

Are the two words interchangeable, or do they have different meanings?

Answer 1

I actually mentioned several answers to this question in an essay I wrote last year. This is just a synopsis of what I wrote, for my specific examples, I refer you to that essay.

1. Malbim offers two ways of differentiating between the terms. First, he argues that the word yerusha is related to the word reshut (“domain” or “charge”) and simply denotes the transfer of property from one party’s domain to another’s. Nachala, on the other hand, refers specifically to the transfer of property in the transgenerational continuum of parent to child.
2. Malbim also explains that yerusha focuses on the inheritance as a legal transfer of property whether or not it was sanctioned by the inheritee, while nachala refers specifically to when the inheritor willingly bequeaths his belongings to his inheritee.
3. Rabbi Shmuel Dovid Luzzatto (1800-1865), known as Shadal, posits a fundamental difference between the Hebrew words nachala and yerusha. He proposes that the word nachala denotes one who receives his inheritance as part of a greater undertaking of divvying up a specific estate. One who receives a nachala does so alongside others who also receive their portion. Shadal even contends that the word nachala is related to the word chelek (“portion”), as both words contain the CHET-LAMMED combination.
4. Others explain that nachala refers specifically to the passage of inheritance from father to son, while yerusha denotes any form of inheritance between relatives, even if not to one’s direct descendants.
5. Rabbi Samson Raphael Hirsch (1808-1888), in an almost-prophetic synopsis of current events, identifies the difference between yerusha and nachala as reflective of two opposing ways in which the younger generation may relate to the older generation. In one model, the younger generation views itself as primary, rejects its connection to the past, and takes for itself everything the elders had built up. In such a case, the inheritance of the younger generation may aptly be called a yerusha. In the second model, the younger generation views itself as the continuation of previous generations. Inheritance under this more conservative paradigm is called nachala because, like a river (nachal), it flows seamlessly and naturally. In this, preferred model, there is no disconnection or repudiation, as both the older and younger generations are of one continuum, and the young appreciate the old.

Answer 2

Partial answer:

I love this question, because I have used it in a few of my Rosh Hashanna or Yizkor sermons in the past.

I am quite certain that Art Scroll (Stone) Chumash explains this difference in the 2nd verse that you cited. I don't have access to the source before me now, so, I am summarizing from what I recall. I'll try to edit in later when I can locate this source.

He explains that נחלה means "inheritance" and it comes from the root form נחל meaning a stream. When someone receives an inheritance, it is a gift that flows from one generation to the next, but as with any flow, it eventually stops at some point. For example, when one receives money as part of the inherited estate, one may use it as he wishes for himself. Once the money has been used, it's not around to pass to the next generation.

I have to research the other usages. The last verse that you cited which has both is curious.

By contrast, מורשה means "heritage". Rash"i and Ramba"n (among others) explain that a מורשה is an item that becomes a continuous endless "gift" that is required to be passed to all future generations until the end of time. This is why the Torah is called מורשה .

Rabbi Riskin gives the same explanation of these two words but expands on the idea by claiming that an inheritance is given over easily. a heritage is given via much intensive work. he also emphasizes that together with the Torah, as mentioned in the verse that you cited, the land of Israel is also called a Morasha (Shemot 6:9.) These are the only two items that the Torah calls a morasha.

Answer 3

Morasha is not an inheritance which the inheritor can dispose of if he wishes. It is more of an heirloom which he must hand over to future generations intact. The inheritor is not the owner but merely a trustee. The Torah and Eretz Yisroel are the only two examples.
