Adjuration
What Is Adjuration?
Adjuration refers to the solemn act of placing someone under oath, or of making an earnest, binding appeal in the name of God. It is distinct from a simple request or command because it invokes divine authority and carries the weight of sacred obligation. To adjure someone is to require them to speak or act truthfully as before God Himself.
In the biblical world, an adjuration was among the most serious forms of human speech. It bridged the gap between ordinary conversation and the sacred realm, calling upon God as witness and judge. The person adjured was bound not merely by social convention but by their relationship with the living God.
Adjuration in the Old Testament
Several Hebrew words convey the concept of adjuration. The most common are forms of shabha (to cause to swear) and alah (to take or impose an oath). These appear in a variety of contexts:
Legal testimony: Leviticus 5:1 addresses the situation where someone "hears a public adjuration to testify" but refuses to come forward with what they know. Withholding testimony after being placed under oath was itself a sin requiring a guilt offering. Proverbs 29:24 reinforces this, noting that the accomplice of a thief who "hears the curse" (the adjuration to testify) but says nothing brings trouble on himself.
Military oaths: In 1 Samuel 14:24, King Saul placed the army under a solemn oath during battle against the Philistines, cursing anyone who ate food before evening. His son Jonathan, unaware of the oath, ate honey and was nearly executed for the violation, illustrating both the binding power and the potential danger of rash adjurations.
Prophetic charges: Joshua pronounced a solemn oath-curse on anyone who would rebuild Jericho (Joshua 6:26), a ban that was fulfilled centuries later when Hiel of Bethel attempted the rebuilding at the cost of his sons' lives (1 Kings 16:34).
Solemn appeals: The Song of Solomon uses adjuration in a different key, as the beloved repeatedly charges the daughters of Jerusalem: "I adjure you, O daughters of Jerusalem, do not stir up or awaken love until it pleases" (Song of Solomon 2:7; 3:5; 8:4).
Adjuration in the New Testament
The most dramatic New Testament adjuration occurs during the trial of Jesus. The high priest Caiaphas said to Him, "I adjure you by the living God, tell us if you are the Christ, the Son of God" (Matthew 26:63). The Greek word used here, exorkizo, means to put someone under oath or to extract testimony by invoking God's name. Jesus, placed under this most solemn form of oath, responded directly: "You have said so" (Matthew 26:64), and proceeded to describe the coming of the Son of Man.
Adjuration also appears in encounters with demons. When Jesus met the Gerasene demoniac, the unclean spirit cried out, "I adjure you by God, do not torment me" (Mark 5:7). Here the demon itself used the language of solemn oath, attempting to bind Jesus by divine authority, a remarkable inversion, since Jesus was the very authority being invoked.
In Acts 19:13, itinerant Jewish exorcists attempted to adjure demons "by the Jesus whom Paul proclaims." The attempt backfired disastrously when the evil spirit replied, "Jesus I know, and Paul I recognize, but who are you?" and attacked them. This episode underscores that adjuration derives its power not from the formula itself but from a genuine relationship with the authority invoked.
Paul himself used adjuration in his letters, solemnly charging the Thessalonians: "I adjure you by the Lord that this letter be read to all the brothers" (1 Thessalonians 5:27).
The Relationship Between Adjuration and Truthfulness
The biblical practice of adjuration rests on the conviction that God is the ultimate guarantor of truth. When a person is placed under oath, they are acknowledging that God sees, hears, and will hold them accountable for their words. This is why perjury, lying under oath, was regarded as an especially grievous sin. It was not merely deception between human parties but an affront to God Himself.
Jesus addressed the broader issue of oath-taking in the Sermon on the Mount (Matthew 5:33-37), teaching that His followers should be so consistently truthful that elaborate oaths become unnecessary: "Let your 'yes' be 'yes,' and your 'no,' 'no.'" This does not abolish the practice of solemn oath but calls believers to a standard of integrity where every word carries the weight of an adjuration.
Adjuration and the Character of God
Ultimately, the practice of adjuration reflects something about God's own nature. Hebrews 6:13-18 notes that when God made His promise to Abraham, "since he had no one greater by whom to swear, he swore by himself." God's own oath-taking guarantees the absolute reliability of His promises. Human adjuration, at its best, is an echo of this divine commitment to truth.
Biblical Context
Adjuration appears in legal contexts (Leviticus 5:1; Proverbs 29:24), military oaths (1 Samuel 14:24), prophetic curses (Joshua 6:26), love poetry (Song of Solomon 2:7), the trial of Jesus (Matthew 26:63), demonic encounters (Mark 5:7), failed exorcism (Acts 19:13), and apostolic charges (1 Thessalonians 5:27). It spans both testaments and multiple literary genres.
Theological Significance
Adjuration underscores the biblical conviction that speech carries moral weight, especially when God's name is invoked. It reflects the seriousness of truth-telling before God and points to God Himself as the ultimate guarantor of truth. The high priest's adjuration of Jesus at His trial became the occasion for Christ's clearest public declaration of His divine identity. Jesus' teaching on oaths calls believers to a standard of truthfulness that makes adjuration less necessary, not because oaths are wrong, but because integrity should pervade all speech.
Historical Background
Oath-taking was universal in the ancient Near East. Mesopotamian, Egyptian, and Hittite legal texts all contain formulas for placing witnesses under oath, often invoking deities as guarantors. In Israelite practice, oaths were typically sworn by the name of Yahweh (Deuteronomy 6:13). The Mishnah later elaborated detailed rules about which oaths were binding. In the Greco-Roman world, oaths were administered in courts and civic assemblies, and the Romans required oath-taking in military, legal, and political contexts.
