2 Samuel 23:5

5. Although my house be not so with God; yet he hath made with me an everlasting covenant, ordered in all things, and sure—"the light of the morning," that is, the beginning of David's kingdom, was unlike the clear brilliant dawn of an Eastern day but was overcast by many black and threatening clouds; neither he nor his family had been like the tender grass springing up from the ground and flourishing by the united influences of the sun and rain; but rather like the grass that withereth and is prematurely cut down. The meaning is: although David's house had not flourished in an uninterrupted course of worldly prosperity and greatness, according to his hopes; although great crimes and calamities had beclouded his family history; some of the most promising branches of the royal tree had been cut down in his lifetime and many of his successors should suffer in like manner for their personal sins; although many reverses and revolutions may overtake his race and his kingdom, yet it was to him a subject of the highest joy and thankfulness that God will inviolably maintain His covenant with his family, until the advent of his greatest Son, the Messiah, who was the special object of his desire, and the author of his salvation.
