SEV Biblia, Chapter 12:19 También se pasaron a David algunos de Manasés, cuando vino con los filisteos a la batalla contra Saúl, aunque no les ayudaron; porque los sátrapas de los filisteos, habido consejo, lo despidieron, diciendo: Con nuestras cabezas se pasará a su señor Saúl.
John Gill's Bible Commentary Ver. 19. And there fell some of Manasseh to David , etc.] Of the tribe of Manasseh; they took his part, and on his side, and joined him: when he came with the Philistines against Saul to battle ; which was a strong proof of their cordial attachment to him: but they helped them not : the Philistines; neither David nor his men, nor the Manassites that joined them: for the lords of the Philistines, upon advisement ; counsel taken among themselves: sent him away; that is, David and his men: saying, he will fall to his master Saul, to the jeopardy of our heads ; meaning, that he would go off with his troops to Saul, and betray them into his hands, and with their heads make his peace with him, (see 1 Samuel 29:4).
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.
