וסכת על הארן means AND THOU SHALT SCREEN THE ARK — וסכת denotes screening and it is the correct term to use, for it (the veil) formed a partition (cf. Rashi on Exodus 35:12).

וערכת את ערכו AND SET ITS ROWS — the two piles of the show-bread.

ויפרש את האהל AND HE SPREAD THE TENT The אהל is the curtains of goats’ skins.

את העדות THE TESTIMONY — the Tablets.

על ירך המשכן צפנה UPON THE SIDE OF THE DWELLING NORTHWARD — i. e. in the northern half of the width of the house (not by the northern wall) (Yoma 33b).

ירך — This must be understood at the Targum renderd it: צדא. The real meaning is “thigh”, but the side of anything is just like the thigh which is at a person’s side.

ויקטר עליו קטרת AND HE CAUSED THE INCENSE OF AROMATICS TO ASCEND UPON IT in the morning and in the evening, as it is said, (Exodus 30:7, 8) “[And Aaron shall cause incense of aromatics to ascend thereon in fumes] every morning when he trimmeth the lamps, [and when he trimmeth the lamps at even etc.]”.

ויעל עליו וגו׳ AND OFFERED UPON IT etc. Not only during the first seven days of the consecration of Aaron and his sons during which Moses set the dwelling up and then dismantled it, but also on the eighth day of the consecration which was the day of the final erection of the dwelling for its ordinary purposes did Moses officiate and offer the congregational sacrifices except those which had been commanded exclusively for that very day, as it is said, (Leviticus 9:7) “[And Moses said to Aaron], approach unto the altar and offer etc.

את העלה THE BURNT OFFERING — the daily burnt offering.

ואח המנחה AND THE MEAL OFFERING — The meal offering brought together with the libation which was made with the daily burnt offering, at it is said, (Exodus 29:40) “[And with the one lamb] (of the daily burnt offering) shall be brought a tenth deal of flour mingled with … oil; [and the fourth part of a hin of wine for a libation …]”.

ורחצו ממנו משה ואהרן AND MOSES AND AARON [AND HIS SONS] LAVED [THEIR HANDS] — On the eighth day of the consecration all of them mentioned here, including Moses, were alike in respect of the priestly office. The translation of ורחצו in the Targum should therefore be ומקדשין, and they were hallowing (i. e. they then hallowed their hands and their feet), for on that day Moses laved his hands together with them (Aaron and his sons).

ובקרבתם — This is equivalent to ובקרבם, and has an imperfect sense, the same as כשיקרבו. when they were approaching.

ולא יכל משה לבא אל אהל מועד AND MOSES WAS NOT ABLE TO COME INTO THE APPOINTED TENT — But another verse says, (Numbers 7:89) “And when Moses came into the appointed tent [to speak with Him then he heard the voice]”! There comes, however, a third verse and reconciles these apparently contradictory verses, for it says here כי שכן עליו הענן “For (or when) the cloud abode thereon (on the appointed tent)”. Hence you may say: so long as the cloud was upon it “he was not able to come into the appointed tent”, but as soon as the cloud disappeared he entered it and spoke with Him (Sifra, Braita d'Rabbi Yishmael 18).

לעיני כל בית ישראל בכל מסעיהם [THE CLOUD WAS ON THE TABERNACLE] … IN THE SIGHT OF ALL THE HOUSE OF ISRAEL, THROUGHOUT ALL THEIR JOURNEYS — At every מסע which they made (according to Rashi this means: at every station at which they stopped) the cloud rested upon the Tabernacle in the place where they encamped. A place where they encamped is also called מסע (the literal meaning of which is “journey”). Similar is, (Genesis 13:3) “And he went on to his resting places (למסעיו)“ (cf. Rashi on this verse); similar also is, (Numbers 33:1) “These are the מסעי” — “the places of encampment”. Because from the place of encampment they always set out again on a new journey therefore all the different stages of their journeys (including the places where they encamped) are called מסעות.
