קח את הלוים, “take the Levites;” this line was said on the day that the Tabernacle had been erected; (Talmud, tractate Gittin 60) seeing that the laws pertaining to the Levites were recorded in writing on that day, as on that day they commenced the part of their service that involved their daily songs of praise. The paragraph was written in chronological order, and the two previous paragraphs, one of which commenced with הקרב את מטה לוי, (Numbers 3,6) and the other which commenced with the words: ואני הנה לקחתי את הלוים, (Numbers 3,12) these paragraphs referred to the position where the Levies encamped around the Tabernacle. After the Tabernacle had been erected and the positioning of the flags had been arranged and the lights of the menorah had been kindled, G-d ordered Moses to command the Levites to commence their daily service. The paragraph dealing with the Levites’ service was written next to that of the kindling of the lights in order to tell us that the priests were to busy themselves with that at the same time as when the Levites were performing their service. Apart from that the Levites will assist the Kohanim in their service.

V. 10. יום אשר וגו׳ ist Objekt des ganzen vorhergehenden Satzes: den Tag, an welchem du deinem Gotte gegenüber standest, an welchem Gott, dein Gott, dir persönlich entgegengekommen und du vor Ihm, "seines Dienstes gewärtig" gestanden. Das heißt ja überall עמד לפני (siehe Bamidbar 3, 6). —
