Charles Ellicott Commentary Leviticus 24:2

"Command the children of Israel, that they bring unto thee pure olive oil beaten for the light, to cause a lamp to burn continually." — Leviticus 24:2 (ASV)

Command the children of Israel. —This is the only other occasion in Leviticus on which God orders Moses to “command,” instead of imparting or communicating His will. (See Leviticus 6:1 in Hebrew, and Leviticus 6:9 in English.) This command, however, occurs almost literally in Exodus 27:20-21.
