The Testament of Jacob is a work now regarded as part of the Old Testament apocrypha. It is often treated as one of a trio of very similar works called the Testament of the Patriarchs, the other two of which are the Testament of Abraham and Testament of Isaac, though there is no reason to assume that they were originally a single work. All three works are based on the Blessing of Jacob, found in the Bible, in their style. Christian elements are usually regarded as later additions to what were originally purely Jewish works.

The Testament of Jacob begins with Jacob being visited by the archangel Michael who told of his impending death. Jacob was then taken on a visit to heaven, where he first sees the torture of the sinful dead, then later meets the deceased Abraham. In this Testament, it is the angels that Jacob meets who deliver the bulk of the sermonising passages.

The testament opens 'in the name of the Father, the Son, and the Holy Spirit, the one God'. God sends the archangel Michael to Jacob to tell him that it is time for him to die and go to heaven to join his father Isaac and grandfather Abraham. Jacob accepts this and God blesses him.
