Charles Ellicott Commentary Leviticus 6:8

"And Jehovah spake unto Moses, saying," — Leviticus 6:8 (ASV)

And the Lord spake unto Moses, saying. —This is the fourth instance in which this formula is used in Leviticus (Leviticus 5:14; Leviticus 6:1). As in the former passages, it introduces a further communication to the Lawgiver.

Until now, the law pointed out to the people under what circumstances and how they are to bring their sacred oblations. Now, directions are given to the priests how to conduct the sacrificial service of the people.
