וידבר ד’ אל משה בהר סיני לאמר…(בהר כה:א)

The word בה״ר is an acronym for “העמדת במרחב רגלי” (תהילים לא:ט)—“You have set my feet in a place of expansiveness.” This alludes to the idea that even when a person is in a state of “בהר”—a state of elevation, where everything is going well—he must remain “סיני.”

The word “סיני” represents humility, just as Har Sinai was chosen for Matan Torah, specifically, because of its lowliness. The message is that even in times of success and plenty, a person must continue to conduct himself with ענוה and lowliness.
