In the tabernacle of the congregation—where the Lord spake with Moses "face to face" (Exodus 33:11), and where all the laws of Leviticus had been given (Leviticus 1:1). On the first day of the second month, in the second year.
On the first day of Zif (or Ijar); a year and a fortnight since the exodus, ten months and a half since their arrival at Sinai, and a month since the tabernacle had been set up.
