Biblical Context:
Gehazi, the servant of the prophet Elisha, is a figure whose actions and experiences are recorded in the books of 2 Kings. His testimony to the king is a significant event that highlights the miraculous works of God through Elisha and serves as a narrative of divine providence and justice.

Scriptural Reference:
The account of Gehazi's testimony to the king is found in 2 Kings 8:1-6. This passage occurs after Gehazi's earlier misdeeds, where he deceitfully acquired gifts from Naaman, the Syrian commander, and was subsequently struck with leprosy as a consequence (2 Kings 5:20-27).

Narrative Summary:
In 2 Kings 8:1-6, Gehazi is found recounting to the king of Israel the great deeds performed by Elisha. The timing of this testimony is providential, as it coincides with the return of the Shunammite woman, whose son Elisha had previously raised from the dead (2 Kings 4:18-37). The Shunammite woman had left her land during a seven-year famine, as instructed by Elisha, and now sought the king's intervention to reclaim her property.

Key Verses:
2 Kings 8:4-5 states, "Now the king was talking to Gehazi, the servant of the man of God, saying, 'Please relate to me all the great things that Elisha has done.' And as Gehazi was telling the king how Elisha had restored the dead to life, behold, the woman whose son he had restored to life came to appeal to the king for her house and her land."

Theological Significance:
Gehazi's testimony serves multiple purposes within the biblical narrative. Firstly, it underscores the authenticity and power of Elisha's prophetic ministry. By recounting the miracles, Gehazi affirms the divine authority vested in Elisha, which in turn reflects the sovereignty and faithfulness of God.

Secondly, the timing of the Shunammite woman's arrival as Gehazi speaks of her son's resurrection is a testament to God's providential care. It illustrates how God orchestrates events to fulfill His purposes and provide for His people. The king, moved by the testimony and the woman's plea, orders the restoration of her property, demonstrating God's justice and mercy.

Character Study:
Gehazi's role in this narrative is complex. Despite his earlier failings, he is positioned as a witness to God's miraculous works. This suggests a theme of redemption and the possibility of being used by God despite past transgressions. Gehazi's presence in the king's court, even as a leper, indicates that his knowledge of Elisha's deeds was valued and sought after.

Historical and Cultural Insights:
In the ancient Near Eastern context, the role of a prophet's servant was significant, as they were often privy to the prophet's actions and teachings. Gehazi's testimony would have carried weight, given his close association with Elisha. Additionally, the king's interest in Elisha's miracles reflects the broader cultural recognition of prophets as intermediaries of divine power.

Conclusion:
Gehazi's testimony to the king is a pivotal moment that highlights the intersection of divine intervention and human affairs. It serves as a reminder of God's ability to work through individuals and circumstances to achieve His divine purposes, offering hope and restoration to those who seek Him.
