וַיִּקְרָא אֶל מֹשֶׁה וַיְדַבֵּר ה’ אֵלָיו מֵאֹהֶל מוֹעֵד לֵאמֹר
And He called to Moshe, and Hashem spoke to him from the Ohel Mo’ed saying…
Hashem would “call to Moshe” to relate more parts to the Torah via prophecy. Rashi comments that Hashem “called to Moshe” for each new prophecy, but for subsections within a prophecy (demarcated by a space in the Torah) there was no additional “calling”. Why then are there spaces? Hashem literally paused while teaching Moshe so that he had a few moments to mull over what he just learned. How much more so when we are learning do we need to give some time to absorb what we learn.
Rav Moshe Feinstein writes that we can learn an important lesson from this. Even though the breaks were important, there was no special “calling” for them. Though one is allowed to pause his learning for certain matters, that doesn’t mean that it’s importance equals that of the actual Torah study.
Torah study feeds our special connection with Hashem, and there is no substitute for it.
