Yahweh’s perception of Israel is clear: “Israel is my son, my firstborn” (Exod 4:22); “Out of Egypt I called my son” (Hos 11:1). As Abraham, Yahweh’s portion (Deut 32:9), had been the new Adam, so Israel, the collective progeny of Abraham, was also the new Adam. Adam was Yahweh’s son. Israel was Yahweh’s son.
