Acts 13:22

And when He had removed him, he raised up unto them David to be their king, to whom also He gave testimony and said, I have found David, the son of Jesse, a man after Mine own heart, which shall fulfill all My will.

Whether the invitation came to Paul with or without his seeking, he at once made use of it. Arising and holding out his hand in a gesture inviting attention, he addressed his hearers as men of Israel and those that feared God. The many references to the history of the children of Israel, which are found also in the sermons of Peter, but especially in that of Stephen, would interest not only the Jews, but prove highly instructive to the proselytes and strangers present as well. There is a certain amount of appeal to the national pride of the people, for it was the God of this nation of Israel that chose their fathers as His own from among all nations of the world. By His blessing they increased not only in numbers, but in strength and power as well, while they were strangers in the land of Egypt. With uplifted arm, then, by the application of His almighty strength, He led them forth from the land of Egypt For forty years, out in the wilderness, He surrounded and bore them with solicitous care in spite of all their ingratitude. In the land of Canaan, to which the Lord brought the children of Israel, He destroyed utterly seven heathen nations before them, the Girgashites, the Amorites, the Hittites, the Perizzites, the Canaanites, the Hivites, and the Jebusites, Exodus 23:23; Joshua 3:10, dividing the land to the conquerors by lot. A space of some four hundred and fifty years, counting from the arrival of the people in Canaan to the final subjugation of the heathen nations at the time of David, was needed to carry out this command of the Lord. The last and most renowned of the judges was Samuel, the prophet. When Samuel had grown old, the people demanded of him a king, and God gave them Saul, the son of Kis, who reigned for forty years. But Saul did not bring his people the promised salvation, it being necessary for God to remove or depose him from the throne, 1 Samuel 15:16; Daniel 2:21. But after Saul's removal the throne was given to David, whom God raised up from the lowly in the land, and of whom He bears witness that He found David, the son of Jesse, to be a man according to His own heart, willing and able to perform all His will. In ascribing these words to God, Paul bears witness to the inspiration of the Old Testament, for his words, instead of being a quotation of one single passage, are a compilation from several verses, Psalms 89:20 and 1 Samuel 13:14. The testimony of the Old Testament, in all its parts, is true, since the Lord spoke through His servants.
