Concept of God in the Old Testament

Jews consider themselves pioneer of monotheism among the worlds religions and consider monotheism in Christianity and Islam examples of more or less influenced by Jewish monotheism. But the study of Old Testament shows that polytheism and idolatry prevailed among the Jews for centuries; even after Moses prophecy. After leaving idolatry and polytheism, their monotheism was monolatrism; that is the worship of a single deity (while believing in the existence of others). Since Jeremiah, Ezekiel and second Isaiah, monotheism entered the Jewish religious literature, but the roots of polytheism among the Jews were never drained and finally re-emerged in various forms in Jewish mysticism. This article attempts to survey the concept of God in the Old Testament.
