12:17 The God of our fathers - He calls God, the God of our fathers, both his fathers and theirs; thus he minds them, not to deal ill with him; for they were both descendents from the same patriarchs, and servants of the same God. And thus he encourages himself to believe, that God would right him, if he was abused. For he was the God of his fathers; therefore a blessing was entailed upon him: and a God to all Israel in particular, as well as a Judge to all the earth.
12:1-22 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 path of duty. Those who break through, and overcome in these attempts, will 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 are under the influence of the Spirit, we shall desire to have our lot among them, and to declare ourselves on their side; if in faith and love we embrace the cause of Christ, he will receive, employ, and advance us.
