The special revelation which Moses received is characterized by the word Yahweh (Yahweh) as a name for God. This name, according to the well-authenticated report of
Ex 6:3 (P), which is supported also by E, had not been "known" to the fathers. This does not necessarily mean that nothing had been known of this name. Babylonian prayers often speak of an "unknown god," and in doing this refer to a god with whom those who prayed had not stood in personal relation. The God of the fathers appeared to Moses, but under a name which was not familiar to the fathers nor was recognized by them. In agreement with this is the fact that only from the time of Moses proper names compounded with some abbreviation of Yahweh, such as Yah, Yahu, Yeho, are found, but soon after this they became very common. Accordingly, it would be possible that such names were in scattered cases found also before the days of Moses among the tribes of Israel, and it is not impossible that this name was familiar to other nations. The Midianites especially, who lived originally at Mt. Sinai, have been mentioned in this connection, and also the Kenites (Stade, Budde), some scholars appealing for this claim to the influence which, according to
Ex 18, Jethro had on the institutions of Moses. However, the matters mentioned here refer only to legal procedure (compare 18:14 ff). We nowhere hear that Moses took over the Yahweh-worship from this tribe. On the contrary, Jethro begins only at this time (
Ex 18:11) to worship Yahweh, the God of Moses, and the common sacrificial meal, according to 18:12, did not take place in the presence of Yahweh, but, accommodating it to the guest, in the presence of Elohim. Then we nowhere hear that the Kenites, who lived together with the Israelites, ever had any special prominence in the service of Yahweh, as was the case, e.g., with the Median Magi, who had charge of the priesthood among the Persians, or with the Etruscans among the Romans, who examined the entrails. Yet the Kenites would necessarily have enjoyed special authority in the Yahweh-cultus, if their tribal God had become the national God of Israel. The only thing that can be cited in favor of an Arabian origin of the name of Yahweh is the Arabic word-form, hawah, for hayah. On the other hand, a number of facts indicate that Ja or Jau as a name for God was common in Syria, Philistia and Babylonia; compare Joram, son of the king of Hamath (
2Sa 8:10), and Jaubidi, the king of this city, who was removed by Sargon. In these cases, however, Israelite influences may have been felt. Friedrich Delitzsch claims to have discovered the names Jahve-ilu and Jahum-ilu on inscriptions as early as the times of Hammurabi. But his readings are sharply attacked. However this may be, the name God as proclaimed by Moses was not only something new for Israel, but was also announced by him (possibly also with a new pronunciation, Yahweh instead of Yahu) with a new signification. At any rate, the explanation in
Ex 3:14 (E), "I AM THAT I AM," for doubting which we have no valid reasons, indicates a depth in the conception of God which far surpasses the current conceptions of the Syrian and the Babylonian pantheon. It would, perhaps, be easier to find analogous thoughts in Egyptian speculations. But this absolute God of Moses is not the idea of speculative priests, but is a popular God who claims to control all public as well as private life.
