Numbers 8:4

1 Yahweh spoke to Moses, saying,

2 Speak to Aaron, and tell him, When you light the lamps, the seven lamps shall give light in front of the lamp stand.

3 Aaron did so; he lighted the lamps of it [so as to give light] in front of the lampstand, as Yahweh commanded Moses.

4 This was the work of the lampstand, beaten work of gold; to the base of it, [and] to the flowers of it, it was beaten work: according to the pattern which Yahweh had showed Moses, so he made the lampstand.

5 Yahweh spoke to Moses, saying,

6 Take the Levites from among the children of Israel, and cleanse them.

7 Thus shall you do to them, to cleanse them: sprinkle the water of expiation on them, and let them cause a razor to pass over all their flesh, and let them wash their clothes, and cleanse themselves.
