Careful word choice[1]
ויקהל משה את-כל-עדת בני ישראל ויאמר אלהם אלה הדברים אשר-צוה יקוק לעשת אתם: ששת ימים תעשה מלאכה וביום השביעי יהיה לכם קדש שבת שבתון ליקוק וגו’ ויאמר משה אל-כל-עדת בני-ישראל לאמר זה הדבר אשר-צוה יקוק לאמר: קחו מאתכם תרומה ליקוק וגו’
Moshe congregated the entire assembly of the Children of Israel, and said to them: “These are the matters which Hashem commanded you, to perform them. Six days work shall be done and on the seventh day it shall be Holy, a restful Shabbos for Hashem…” Moshe said to the entire assembly of the children of Israel, saying: “This is the matter which Hashem commanded, saying: ‘Take from yourselves a donation for Hashem…’”[2]
The beginning of this week’s parsha contains many oddities and inconsistencies. First, we are told that Moshe congregated the entire Jewish people to tell them about the observance of Shabbos. Why was there a need to teach them about Shabbos? This isn’t the first time they’ve heard about it. In fact, it was already repeated in last week’s parsha! What’s being added this time around? Furthermore, why is it stressed that Moshe congregated them? We don’t find this action associated with any other mitzvah in the Torah.
