Topical Lexicon
Definition and Usage

Strong’s Greek 4901 denotes the act of God “bearing witness together with” the apostolic proclamation. It appears once in the Greek New Testament in Hebrews 2:4, where the writer explains how the Lord confirmed the message of salvation “by signs, wonders, various miracles, and by gifts of the Holy Spirit distributed according to His will”. The term emphasizes a coordinated, cooperative testimony—God acting in real time to validate the preached word.

Context in Hebrews

Hebrews 2:1–4 forms an exhortation not to “drift away” from the gospel. The argument proceeds from (1) the authoritative word spoken through angels at Sinai, to (2) the greater word spoken by the Lord, to (3) the divine verification of that word. Verse 4 supplies the capstone: God Himself corroborated the apostolic message, joining His testimony to theirs. The rare verb underscores that the confirmation was neither accidental nor peripheral; it was an intentional, redemptive-historical event.

Divine Testimony through Signs

1. Signs and Wonders: Miraculous acts that arrest attention (Acts 2:22; Acts 5:12).
2. Various Miracles: Demonstrations of divine power over nature, sickness, and demonic forces (Acts 19:11).
3. Gifts of the Holy Spirit: Charismata granted for edification and mission (1 Corinthians 12:4–11).

By linking these phenomena to the verb, the author teaches that supernatural manifestations served a specific theological purpose: authenticating the once-for-all gospel delivered by the Son (Hebrews 1:1–2).

Old Testament Background

Scripture consistently requires multiple witnesses for legal confirmation (Deuteronomy 19:15). Prophetic proclamations were likewise validated by fulfilled signs (Exodus 4:1–9; 1 Kings 18:36–39). Hebrews adopts this jurisprudential principle, now applying it to the new covenant revelation: God is the corroborating party who provides incontestable evidence.

Theological Significance

• Revelation and Verification: The God who speaks also authenticates, maintaining harmony between word and deed (Numbers 23:19).
• Trinitarian Cooperation: The Father testifies (Hebrews 2:4), the Son declares (Hebrews 2:3), and the Spirit distributes gifts; each person acts without division of purpose.
• Soteriological Urgency: Neglecting a salvation so divinely attested leaves no excuse (Hebrews 10:28–29).

Historical Perspective

In the apostolic era, public miracles and charismatic gifts functioned as “accreditation credentials” (cf. 2 Corinthians 12:12). Early Christian writers—Justin Martyr, Irenaeus—refer to ongoing healings and deliverances as evidence of the risen Christ’s power. The concentrated occurrence of such signs during the foundational period aligns with Hebrews’ timeframe, illustrating how God “bore witness together with” the first preachers.

Application for Ministry

• Confidence in the Gospel: Since God has already supplied conclusive testimony, contemporary proclamation rests not on human ingenuity but on divine validation recorded in Scripture.
• Expectation of God’s Activity: While the canonical foundation is complete, the Lord still confirms His word through providence, answered prayer, and Spirit-empowered works that align with biblical truth.
• Integrity of Witness: Preachers must live consistently with a message God Himself has endorsed; hypocrisy undercuts the very testimony Hebrews describes.
