"Ugaritic polytheism is expressed as a monism through the concepts of the divine council or assembly and in the divine family. The two structures are essentially understood as a single entity with four levels: the chief god and his wife (El and Asherah); the seventy divine children (including Baal, Astarte, Anat, probably Resheph as well as the sun-goddess Shapshu and the moon-god Yerak) evidently characterized as the stars of El; the head helper of the divine household, Kothar wa-Hasis; and the servants of the divine household, who include what the Bible understands to be "angels" (in other words, messenger-gods).

"This four-tiered model of the divine family and council apparently went through a number of changes in early Israel. In the earliest stage, it would appear that Yahweh was one of these seventy children, each of whom was the patron deity of the seventy nations. This idea appears behind the Dead Sea Scrolls reading and the Septuagint translation of Deuteronomy 32:8-9. In this passage, El is the head of the divine family, and each member of the divine family receives a nation of his own: Israel is the portion of Yahweh. The Masoretic Text, evidently uncomfortable with the polytheism expressed in the phrase "according to the number of the divine sons," altered the reading to "according to the number of the children of Israel" (also thought to be seventy)."
