G3140 is a verb for testifying, bearing witness, attesting something, or giving a favorable report. Its seventy-six governed forms include testimony about Jesus, God's works, Scripture, people, conduct, truth, and disputed claims. John contains the largest concentration, where John the Baptist, Jesus, the Father, works, Scripture, eyewitnesses, and others testify.
Elsewhere the Law and Prophets attest God's revealed righteousness, the prophets testify about forgiveness through Jesus, the Lord confirms the message of grace, and people receive favorable testimony or commendation. The verb therefore does not always mean apostolic eyewitness proclamation, courtroom speech, evangelism, or martyrdom. Its subject, object, grammar, and narrative evaluation determine who testifies, what is attested, and whether the testimony is favorable, disputed, true, or false.
Acts 1:8 uses the related person-noun G3144 for witnesses rather than this G3140 verb.
John supplies thirty-three of the governed verb's seventy-six forms; the remaining uses bring its full reach to seventy-two verses in fourteen books. Acts, Hebrews, the letters, and Revelation broaden G3140 from direct testimony to attestation, commendation, and favorable report.

The testimony of Scripture serves Jesus' argument and cannot be detached from the hearers' refusal to come to Him.

John ties the eyewitness act, the testimony-content, truth, and intended belief together.
All the prophets testify about Him that everyone who believes in Him receives forgiveness of sins through His name.”
Prophetic testimony supports Peter's proclamation of forgiveness through Jesus.
But now, apart from the law, the righteousness of God has been revealed, as attested by the Law and the Prophets.
The Law and Prophets function as attesting witnesses within Paul's argument about God's righteousness.
By faith Abel offered God a better sacrifice than Cain did. By faith he was commended as righteous when God gave approval to his gifts. And by faith he still speaks, even though he is dead.

G3140 teaches that testimony is accountable speech. John places testimony about Jesus within a network of persons, works, Scripture, and eyewitness report, and it repeatedly distinguishes a claim from the reasons for receiving it as true. Other books use the same verb for prophetic attestation, favorable reputation, God's approval, and commendation. This breadth keeps the church from turning testimony into performance or private certainty.
Christians should speak truthfully about Christ and God's work, but they must not claim apostolic eyewitness status they do not possess, treat personal experience as self-validating, or manipulate hearers as though human skill creates faith. Faithful testimony can be bold and costly, yet the verb itself neither promises persuasive results nor requires suffering as proof of sincerity.
John.19.35
The governed verb uses forty-two surface forms and forty parsing patterns. Active and passive forms can describe giving testimony, being attested, or receiving a favorable report, so voice, syntax, and context are essential.
