<b> And Moshe went and spoke these words to all of Israel:</b> The expression "went" is nothing but [an indication of] rebuke, as it is stated (Psalms 46:9), "Go and see the wonders of God." At the end of Ecclesiastes, it is written (Ecclesiastes 12:11), "The sayings of the wise are like goads" - just like this goad directs the cow to its furrows, so [too] do the words of Torah direct the heart of those that learn it to the good path. "And it is like nails (<i>masmerot</i>) that are planted" - just like this nail is planted, so [too] are words of Torah. And just like a planting (sapling) is fruitful and multiplies, so [too] do the words of Torah become fruitful and multiply to find an explanation about them. "They are given from one shepherd" - even though these are rendering impure and those are rendering pure, these are forbidding and those are permitting, Moshe said all of them from the mouth of the Almighty. But it is written, "And it is like shifts (<i>mishmerot</i>) that are planted," with a [letter], <i>shin</i>, to say that there are twenty-four books in the Torah (Bible) - like the number of shifts that David established. Therefore it is written with a <i>shin</i>. And so [too,] in Chronicles, David is spelled fully (<i> dalet-vav- yod-dalet</i>), as its <i>gematraia</i> (numerical equivalent) is twenty-four - corresponding to the twenty-four shifts that David established.
