rate convincing. In one source, e.g. (J), the Israelites dwell by
themselves in a district called Goshen, viii. 22 (cf. Gen. xiv. 10);
in the other, they dwell among the Egyptians as neighbours, so that
the women can borrow jewels from them, iii. 22, and their doors have
to be marked with blood on the night of the passover to distinguish
them from the Egyptians, xii. 22. Again in J, the people number over
600,000, xii. 37; in E they are so few that they only require two
midwives, i. 15. Similar slight but significant differences may be
found elsewhere, particularly in the account of the plagues. In J,
e.g., Moses predicts the punishment that will fall if Pharaoh
refuses his request, and next day Jehovah sends it: in E, Moses
works the wonders by raising his rod. In Exodus, as in Genesis, J
reveals the divine through the natural, E rather through the
supernatural. It is an east wind, e.g., in J, as in the poem, xv.
10, that drives back the Red Sea, xiv. 21a (as it had brought the
locusts, x. 13); in E this happens on the raising of Moses' rod,
xiv. 16. Here again, as in Genesis, we find that E has taken the
first step on the way to P. For this miracle (in E) at the Red Sea,
which in J is essentially natural, and miraculous only in happening
at the critical moment, is considerably heightened in P, who relates
that the waters were a wall unto the people on the right hand and on
the left, xiv. 22.

These three great documents constitute the principal sources of the
book of Exodus; but here, as in Genesis, there are fragments that
belong to a more primitive order of ideas than that represented by
the compilers of the documents (cf. iv. 24-26); there is, besides
the two decalogues, a body of legislation, xx. 23-xxiii. 33; and
there is a poem, xv. 1-18. _The Book of the Covenant_, as it is
called, is a body of mainly civil but partly religious law,
