John Gill's Bible Commentary Ver. 4. And Ishmaiah the Gibeonite, a mighty man among the thirty, and over the thirty , etc.] That came with him, and he had the command of; this man was of Gibeon, another city in the tribe of Benjamin, ( Joshua 18:25) and Jeremiah, and Jahaziel, and Johanan, and Josabad, the Gederathite ; one of Gederah, a city in the tribe of Judah, perhaps on the borders of that and Benjamin; Joram speaks of it as belonging to the country of the city Aelia or Jerusalem.
Matthew Henry Commentary
Verses 1-22 - Here is an account of those who appeared and acted as David's friends while he was persecuted. No difficulties or dangers should keep the sinner from coming to the Savior, nor drive the believer from the pat of duty. Those who break through, and overcome in these attempts, wil find abundant recompence. From the words of Amasai we may learn how to testify our affection and allegiance to the Lord Jesus; his we must be throughly; on his side we must be forward to appear and act. If we ar under the influence of the Spirit, we shall desire to have our lo among them, and to declare ourselves on their side; if in faith an love we embrace the cause of Christ, he will receive, employ, an advance us.
