1. The Foundation of the Principle
The principle of first mention is based on the unity and consistency of Scripture. Since God is the author of all Scripture, He does not contradict Himself. When He introduces a concept for the first time, He establishes its essential meaning. Later uses may expand, clarify, or apply that meaning, but they will not contradict the foundational sense. For example, the first mention of "covenant" in Genesis refers to God's promise to Noah. That first mention establishes that a covenant is a divine, unconditional promise. Later covenants add conditions, but the foundational idea remains.
2. The First Mention of Sacrifice
The first mention of sacrifice in Scripture appears in Genesis 4, where Abel brought of the firstborn of his flock and of their fat. The Lord respected Abel and his offering. This first mention establishes several key truths about sacrifice. First, sacrifice involves the shedding of blood, for Abel brought from the flock. Second, sacrifice is an offering to the Lord, not a mere ritual. Third, sacrifice is acceptable only when offered in faith. Fourth, sacrifice points forward to the perfect sacrifice of Christ, the Lamb of God. This first mention sets the pattern for all subsequent teaching on sacrifice.
3. The First Mention of the Prophet
The first mention of a prophet in Scripture is Abraham, whom God called a prophet in Genesis 20. God said to Abimelech, "He is a prophet, and he will pray for you and you shall live." This first mention establishes that a prophet is one who speaks to God on behalf of others (intercessor) and to others on behalf of God (spokesman). Abraham prayed for Abimelech, and God healed him. This foundational understanding of prophecy as intercessory prayer and divine revelation continues throughout Scripture. Later prophets like Moses, Samuel, and Jeremiah fulfill this pattern.
4. The First Mention of the Kingdom of God
The first mention of the kingdom of God in Scripture is implicit in Genesis 1, where God creates the heavens and the earth and rules over His creation. Explicitly, the first mention of God as King appears in Exodus 15, after the crossing of the Red Sea: "The Lord shall reign forever and ever." This first mention establishes that God's kingdom is His sovereign rule over all creation. Later references to the kingdom of God in the New Testament expand this concept but do not contradict it. The kingdom is God's reign, exercised through His Son, over His people.
5. The First Mention of Love
The first mention of love in Scripture is the love of a father for his son. In Genesis 22, God said to Abraham, "Take now your son, your only son Isaac, whom you love." This first mention establishes that love involves deep affection, sacrifice, and the willingness to give what is most precious. It also points forward to the Father's love for His only Son, Jesus Christ, and His willingness to offer Him as a sacrifice. The first mention of love thus provides the framework for understanding God's love for His people throughout Scripture.
6. The First Mention of the Sabbath
The first mention of the Sabbath appears in Genesis 2, where God rested on the seventh day from all His work. The first mention establishes that the Sabbath is a day of rest following six days of labor. It is rooted in God's own pattern. There is no command to keep the Sabbath in Genesis, but the principle of rest is established. Later, the Sabbath command is given to Israel. The first mention provides the theological foundation: the Sabbath is a creation ordinance, a pattern of rest built into the order of the world.
7. The Limitations of the Principle
The principle of first mention must be applied carefully. It is not an infallible rule, and it cannot override clear later revelation. The first mention of a concept may be implicit or incomplete. For example, the first mention of the serpent in Genesis 3 introduces Satan, but the full revelation of Satan's identity and destiny comes later. The first mention of the seed of the woman in Genesis 3:15 points to Christ, but the specific details of His person and work are revealed progressively. The principle of first mention is a helpful tool, not an absolute law.
8. The Danger of Over-Using the Principle
Some interpreters misuse the principle of first mention by claiming that the first occurrence of a word determines its meaning in every later occurrence. This is a mistake. Words can develop additional meanings over time. The first mention of "law" in Genesis (the law of sin offering) is not the same as the law of Moses. The first mention of "grace" in Genesis (Noah found grace) establishes the concept of unmerited favor, but later uses expand and clarify. The principle is a guide, not a mechanical rule. Later revelation can clarify what was implicit in the first mention.
9. The Principle as a Tool for Tracing Themes
The principle of first mention is most useful as a tool for tracing themes through Scripture. By observing the first mention of a theme, the student can identify its foundational meaning. Then, as the theme appears again, the student can see how later revelation builds upon, applies, or expands the original foundation. This method helps the student see the unity of Scripture. It prevents the error of interpreting a later passage in isolation from its biblical-theological context. The first mention provides the starting point for a biblical theology of any theme.
10. The Example of the First Mention in Practice
To apply the principle of first mention, select a theme such as "redemption." Find its first occurrence. The first mention of redemption in Scripture appears in Exodus 6:6, where God says, "I will redeem you with an outstretched arm." This first mention establishes that redemption is an act of God's power, delivering His people from bondage. Later uses in the Psalms, Isaiah, and the New Testament expand this meaning to include deliverance from sin and death, but they do not contradict the foundational meaning. The first mention provides the key to understanding all later mentions.
Conclusion
The principle of first mention observes that the first time a word, concept, or theme appears in Scripture often establishes its foundational meaning for all subsequent uses. This principle recognizes the unity and consistency of Scripture. It aids interpretation when applied carefully, in harmony with later revelation, and as a tool for tracing themes. It is not an infallible rule but a helpful guide. Let every student of Scripture use the principle of first mention to trace God's truth from Genesis to Revelation.
