בצלאל בן אורי בן חור, “Betzalel, son of Uri, son of Chur;” the reason why the Torah mentions also the grandfather of Betzalel, whereas in the case of his assistant, Oholiov, it mentions only his father, (verse 6) is that Chur had died a martyr’s death in opposing the Israelites‘ dancing around the golden calf. The major function of the Tabernacle was to atone for that sin. This is why his name is mentioned here in connection with the Tabernacle.

ואת בגדי השרד, “and the service garments;” according to Rashi these were not priestly garments, but garments woven alternately of blue wool and red wool, i.e. תכלת וארגמן as described in the portion dealing with the journeys of the Israelites (Numbers 4,7-9). This sounds quite unlikely, as these garments are referred to throughout the Talmud as priestly vestments.

אך את שבתותי שמורו, “but you must observe My Sabbaths;” Moses is to tell the people that although they might have thought that having been commanded to construct a residence for G–d on earth, completing it as soon as possible would override any restrictions that are part of the Sabbath, the Sabbath is not to be desecrated on account of building the Tabernacle.

וביום השביעי שבת וינפש, “but on the seventh day He rested and withdrew into His essence.” Rabbi Yehudah Hachassid said that from this verse we can deduce that the Jew receives an additional soul on the Sabbath. When you read the respective last letters in the last four words of the verse backwards, you get the word שתים, “two.” The Talmud relates an interesting conversation between Rabbi Akiva and Turnusrufus, the wicked Roman governor during part of his life when the latter met him once on the Sabbath. Upon seeing him, the governor asked Rabbi Akiva what was so special on that particular day, to which Rabbi Akiva replied: “how are you different from anyone else?” Turnusrufus wanted to know what kind of an answer this was to his question. The Lord had singled him out to be more honoured than other human beings. Rabbi Akiva told him that the same Lord had singled out the Sabbath to be more honoured than any other day He had created. Turnusrufus then wanted to know why that same G–d performs all manner of work on the Sabbath, such as letting the wind blow, the rain fall, etc., whereas He denied the Jews to work on the Sabbath and to travel on the Sabbath? Rabbi Akiva replied that he was aware that the governor was familiar with the Torah G–d had given the Jews, so that he could ask him, why if two Jews share the same courtyard in front of their houses, what is the reason for the law whereby if each of the homeowners does not enter into an arrangement whereby he foregoes his legal claim to the courtyard, neither of them can move his chattels in that courtyard on the Sabbath, whereas when they each waive their claim, they can both use that courtyard freely? How come, he continued, that if a Jew has a palace owned exclusively by himself, and surrounded by a courtyard as large as the city of Damascus, he is free to move all his chattels all over that courtyard on the Sabbath? Similarly, the Lord Who owns both heaven and earth exclusively, is free to let the wind blow and to let the rain fall without thereby violating the laws of His Sabbath. He added, that if proof were needed for what he had told the Roman governor, let him reflect on the fact that that same Creator observed the Sabbath by not having given the Jews in the desert their heavenly bread, manna on that day, but giving them a double portion on the Sabbath eve, so that they would not go hungry on that day.
