Baruch Levine's commentary on Leviticus/Vayikra is commendable. The Hebrew text is easy to read with the English translation set out alongside it and the commentary appearing below. Levine ably brings modern scholarship as well as rabbinic commentary to bear when discussing the text. However, for my money, a far better commentary on Leviticus has been done by Jacob Milgrom in the Anchor Bible series. Milgrom's work is far more thorough and groundbreaking. I would recommend that you look at Milgrom's commentary before purchasing Levine's.
