1 Yahweh spoke to Moses and said:
2 'Speak to Aaron and say, "When you set up the lamps, the seven lamps must throw their light towards the front of the lamp-stand." '
3 Aaron did this. He set up the lamps to the front of the lamp-stand, as Yahweh had ordered Moses.
4 This lamp-stand was worked in beaten gold, including its stem and its petals, which were also of beaten gold. This lamp-stand had been made according to the pattern Yahweh had shown to Moses.
5 Yahweh spoke to Moses and said,
12 'The Levites will then lay their hands on the heads of the bulls, one of which you will offer as a sacrifice for sin, and the other as a burnt offering to Yahweh, to perform the rite of expiation for the Levites.
18 and now, in place of all the first-born of the Israelites, I have taken the Levites.
19 Of the Israelites, I give the Levites to Aaron and his sons, as dedicated men, to minister in the Tent of Meeting on behalf of the Israelites and perform the rite of expiation for them, so that no disaster befalls the Israelites when the Israelites come close to the sanctuary.'
23 Yahweh spoke to Moses and said:
25 After the age of fifty, he is no longer bound to the ministry; he will have no further duties;
26 but he will still help his brothers to assure the services in the Tent of Meeting, though he himself will no longer have any ministry. That is how you will act as regards the ministry of the Levites.'
The New Jerusalem Bible (NJB) is a Catholic translation of the Bible published in 1985. The New Jerusalem Bible (NJB) has become the most widely used Roman Catholic Bible outside of the United States. It has the imprimatur of Cardinal George Basil Hume.
Like its predecessor, the Jerusalem Bible, the New Jerusalem Bible (NJB) version is translated "directly from the Hebrew, Greek or Aramaic." The 1973 French translation, the Bible de Jerusalem, is followed only "where the text admits to more than one interpretation." Introductions and notes, with some modifications, are taken from the Bible de Jerusalem.
