I Chronicles 12:10

Now these are they that came to David to Ziklag,.... Given him by Achish to live in, when he fled from Saul, Sa1 27:6. while he yet kept himself close, because of Saul the son of Kish; when he was an exile from his own country, and obliged to live retired in a foreign one, because of Saul's persecution of him, and seeking to take away his life: and they were among the mighty men, helpers of the war; not against Saul, with whom David had none, but with the Amalekites, and others, Sa1 27:8.

What the mighty men did towards making David king we read in the foregoing chapter. Here we are told what the many did towards it. It was not all at once, but gradually, that David ascended the throne. His kingdom was to last; and therefore, like fruits that keep longest, it ripened slowly. After he had long waited for the vacancy of the throne, it was at two steps and those above seven years distant, that he ascended it. Now we are here told, I. What help came in to him to Ziklag, to make him king of Judah (v. 1-22). II. What help came in to him in Hebron, to make him king over all Israel, above seven years after (v. 23-40).
