The tribe of Issachar embodies a unique blend of deep-rooted agricultural labor and profound dedication to spiritual and intellectual life. Inherently drawn to peace, stability, and tranquility, the tribe recognized these conditions as essential for personal and national growth. The primary approach among commentators is that Issachar looked upon his geographical inheritance and realized his land was blessed, pleasant, and comfortable. Consequently, he chose to remain at home, fully content with his portion, rather than embarking on distant maritime trade expeditions like the neighboring tribe of Zebulun [רשב״ם, ריב״א, בכור שור, חזקוני].
Conversely, a more spiritual approach views this tranquility not just as physical comfort, but as a mental and intellectual state. Issachar understood that the pursuit of wisdom and Torah study demands free time, physical stillness, and peace of mind. He deliberately chose a lifestyle detached from worldly anxieties and conflicts to achieve perfection of thought [ספורנו, העמק דבר, רבנו בחיי, רש״ר הירש]. Recognizing that the rich soil could provide for his needs without excessive hardship [ספורנו, ריב״א], he was willing to accept whatever responsibilities were required to sustain this way of life.
To maintain this existence, Issachar had to shoulder a significant load, much like a strong beast of burden. On a practical level, this meant willingly accepting the physical exhaustion required for demanding agricultural work [רשב״ם, שד״ל, ריב״א, ביאור יש״ר]. On a spiritual level, the burden represents taking upon oneself the yoke of Torah study and the needs of the community [ספורנו, רש״י]. The very act of lowering one's shoulder demonstrates a profound humility, which is an absolute prerequisite for those who wish to master Torah [רבנו בחיי, צאינה וראינה]. Other perspectives offer different views of this burden. One interpretation suggests it refers to the heavy responsibility of hospitality, with Issachar taking on the effort of hosting members of other tribes who passed through his territory [חזקוני]. Alternatively, based on the translation of Onkelos, lowering the shoulder signifies a readiness for combat, bravely going out to conquer enemy territories along the borders [רש״י, נתינה לגר, מחוקקי יהודה].
The consequences of Issachar's choices led to a life of service, which commentators understand in several distinct ways. From a political and economic standpoint, Issachar preferred to pay heavy taxes and offer portions of his harvest to the kings of Israel or foreign rulers. He willingly gave up his wealth on the condition that he be left alone to live peacefully on his land without being drafted into the military [אבן עזרא, רשב״ם, רלב״ג, ביאור יש״ר]. A spiritual interpretation reframes this concept of taxation as a public service dedicated to the entire nation. Issachar essentially became a living tax by devoting himself entirely to teaching Jewish law, rendering legal decisions, and calculating the complex calendar and leap years for the rest of the tribes [רש״י, רבנו בחיי, צאינה וראינה]. Furthermore, he took on the financial burden of feeding and supporting those who traveled to his land to study Torah [קיצור בעל הטורים, הטור הארוך].
In stark contrast, the military perspective of Onkelos argues the exact opposite reality. Instead of Issachar paying taxes, it was the defeated enemies living within his territory who became subjugated laborers, paying tribute to him [רש״י, נתינה לגר, ביאור שטיינזלץ]. Ultimately, these diverse interpretations reveal the complex character of the tribe. Issachar navigated a path that encompassed intense agricultural labor, deep spiritual diligence, and, when necessary, formidable military courage [ברכת אשר על התורה].
