Jenkins links to the old translation by E. A. Wallis Budge. A new translation by Alexander Toepel is coming out in Old Testament Pseudepigrapha: More Noncanonical Scriptures, vol. 1, a copy of which I expect to hold in my hands in a matter of days.
UPDATE (18 October): I don't know why this pre-post decided to manifest itself early, even with its future posting date intact. Chalk it up to time travel.
