practically certain that these are to be referred to the two
prophetic sources. Cf. the two derivations of the name of Joseph in
consecutive verses whose source is at once obvious: "_God_
(Elohim) has taken away my reproach" (E); and "_Jehovah_ adds
to me another son" (J), Gen. xxx. 23, 24. Cf. also the illustrations
adduced on pp. 13, 14.]

The documents already discussed constitute the chief sources of the
book of Genesis; but there are occasional fragments which do not
seem originally to have belonged to any of them. There were also
collections of poetry, such as the Book of Jashar (cf. Josh. x. 13;
2 Sam. i. 18), at the disposal of those who wrote or compiled the
documents, and to such a collection the parting words of Jacob may
have belonged (xlix.). The poem is in reality a characterization of
the various _tribes; v_. 15, and still more plainly _vv_.
23, 24, look back upon historical events. The reference to Levi,
_vv_. 5-7, which takes no account of the priestly prerogatives
of that tribe, shows that the poem is early (cf. xxxiv. 25); but the
description of the prosperity of Joseph (i.e. Ephraim and Manasseh),
_vv_. 22-26, and the pre-eminence of Judah, _vv_. 8-12,
bring it far below patriarchal times--at least into the period of
the Judges. If _vv_. 8-12 is an allusion to the triumphs of
David and _vv_. 22-26 to northern Israel, the poem as a whole,
which can hardly be later than Solomon's time--for it celebrates
Israel and Judah equally--could not be earlier than David's; but
probably the various utterances concerning the different tribes
arose at different times.

The religious interest of Genesis is very high, the more so as
almost every stage of religious reflection is represented in it,
