For instance, in Numbers 22:22, the Angel of the Lord (often interpreted as a pre-incarnate manifestation of Jesus or the Logos, sometimes referred to as "The Word") confronts the sorcerer Balaam as "his adversary" (ləśāṭān). In this passage, the term "adversary" refers to the Angel's role in opposing Balaam's intentions, not a reference to a specific evil entity. This is not an isolated occurrence; there are other instances in which God or His agents act as a satan (adversary) for the purpose of fulfilling divine will.

One of the most well-known appearances of "satan" occurs in the opening chapters of the Book of Job (Job 1–2). Here, many people mistakenly interpret the adversary before God as "Satan," the devil as conceived in later Christian theology. However, a closer examination of the Hebrew text reveals the definite article "the" (haśśāṭān), which indicates a title rather than a proper name as we do not see definite articles used before Satan’s name in the New Testament. “The adversary” or “the accuser” is, therefore, a more accurate translation. In context, this figure is depicted as a member of the divine council—a heavenly assembly of spiritual beings who serve as God’s heavenly family. This interpretation is supported by verse 6, which describes the "sons of God" gathering before the Lord, a phrase and imagery commonly associated with divine council meetings in Scripture (e.g., Psalm 82, Daniel 7, 1 Kings 22). This adversary’s role is to test the faith and integrity of humans, specifically Job, as part of a divine purpose. While such actions might seem malevolent from a human perspective, they occur within the sovereign will of God and do not suggest the adversary in this context is an evil, fallen being. Instead, this adversary operates under God's authority and serves as an instrument of testing.

The only instance in the Old Testament where "satan" appears without the definite article (i.e., seemingly as a proper name) is in 1 Chronicles 21:1: "Then Satan stood against Israel and incited David to number Israel." This has led some to suggest that this passage refers to the Satan of later Christian theology. However, a parallel account of this same event in 2 Samuel 24:1 provides a crucial clue. There, it states that God Himself incited David to conduct the census as an act of judgment after His anger was kindled against Israel. This discrepancy between the two accounts suggests that "satan" in 1 Chronicles 21:1 may not refer to a distinct spiritual being but rather to God in His role as an adversary to Israel at that moment. This interpretation is consistent with other instances where God or His agents are described as adversaries (e.g., Numbers 22:22).

Satan, as we understand him today—a rebellious and malevolent being who opposes God and leads humanity into sin—makes his clearest appearance in Genesis 3. Here, he is identified as the serpent who deceives Eve, though he is not explicitly named "Satan" in the text. This narrative lays the foundation for his role as the tempter and deceiver in later theology. Beyond Genesis, Satan is alluded to indirectly in prophetic passages such as Ezekiel 28 and Isaiah 14. These chapters describe the downfall of the kings of Tyre and Babylon, but their language and imagery extend beyond the mortal realm, drawing parallels to the pride, corruption, and fall of a more profound figure. For example, Ezekiel 28 portrays a being in Eden, "the anointed cherub" who was cast down due to pride and iniquity, while Isaiah 14 references the fall of "Lucifer, son of the morning," a title often interpreted as a reference to Satan. These passages, though addressing human rulers, have long been understood by many theologians as veiled descriptions of Satan's fall, using the kings’ arrogance and rebellion as mirrors of his own. Together, these texts contribute to the evolving depiction of Satan as the ultimate adversary, whose pride and defiance set the pattern for both spiritual and human corruption.

In summary, the Old Testament usage of "satan" differs significantly from the later theological conception of Satan as a personal, fallen angel and the embodiment of evil. In the Hebrew Bible, "satan" primarily functions as a title or role—one who opposes, tests, or accuses—whether it refers to human beings, spiritual beings, or even God Himself acting in an adversarial capacity. This broader and more nuanced understanding of "satan" challenges us to consider the complexities of God’s sovereignty and how divine purposes are carried out, even through opposition or testing that may appear troubling from a human perspective.
