### sense in the lessons

In the Tanakh and Jewish tradition: In Jacob's blessing, Reuben is "unstable as water," meaning hasty and not steady. Interpretation: Jacob says Reuben loses his place as firstborn because of the wrong he did. The tradition reads his lack of self-control as the reason he loses leadership. In the primary lessons: In science and design lessons: a tall thin tower is unstable; a wide base makes it stable. In safety: unstable cliffs, ice or ladders are dangerous. In news: unstable prices or governments. Phrases: «unstable ground», «emotionally unstable».
