(20) And David rose up early in the morning, and left the sheep with a keeper, and took, and went, as Jesse had commanded him; and he came to the trench, as the host was going forth to the fight, and shouted for the battle. (21) For Israel and the Philistines had put the battle in array, army against army. (22) And David left his carriage in the hand of the keeper of the carriage, and ran into the army, and came and saluted his brethren.
There is somewhat very interesting in this account of David's affection to his brethren. Though he had risen early and come a long journey, yet it is said, he ran to salute his brethren. Precious Jesus! methinks I see thee here. Didst not thou come from thy Father, and our Father, and leave thy sheep above, when thou camest at his command, to see how thy brethren fared below. Thou didst run indeed, blessed Jesus, when thou camest among us for the purpose of salvation, for thy zeal even consumed thee, and thou was straitened, until the baptism of thy sufferings was accomplished. Luke 12:50. The Reader will not overlook I hope, nor forget to connect the history of Joseph, sent on a similar errand by Jacob, with this of David. Surely we do not strain the subject in the idea of somewhat typical in both. See Genesis 37:13-14.
