40:35. If it hung over, they remained in the same place.

40:36. For the cloud of the Lord hung over the tabernacle by day, and a fire by night, in the sight of all the children of Israel throughout all their mansions.

Leviticus Chapter 1

Of holocausts or burnt offerings.

1:1. And the Lord called Moses, and spoke to him from the tabernacle of the testimony, saying:

1:2. Speak to the children of Israel, and thou shalt say to them: The man among you that shall offer to the Lord a sacrifice of the cattle, that is, offering victims of oxen and sheep:

1:3. If his offering be a holocaust, and of the herd, he shall offer a male without blemish, at the door of the testimony, to make the Lord favourable to him.
