### sense in the lessons

In the Tanakh and Jewish tradition: In Sefer Yetzirah, the "decade" is the group of ten Sefirot, the ten basic numbers or powers through which God made the world. Interpretation: Tradition reads the ten as the ten "infinitudes" or utterances that work with the 22 letters to form creation. Pythagoras's followers also thought ten was a holy number. In the primary lessons: In maths and history lessons it is used to measure time: one decade = 10 years, two decades = 20 years. It tells the reader a long time has passed. Phrases: for decades, over the past decade, a decade ago, the next decade.
