2 Samuel 15:18

And all his servants passed on beside him; and all the Cherethites, and all the Pelethites, and all the Gittites, six hundred men which came after him from Gath, passed on before the king.

Ver. 18. Six hundred men which came after him from Gath.] That had stuck to him in all his afflictions; then when he was at Gath, and now also that Absalom was up in arms against him. As any of these six hundred died, others of like fidelity were succenturiated, and set in their room; and these were to David as that Sacra cohors was to the Thebans, who esteemed them the prime of all their strength in battle, a God likewise setteth a high price on such as keep close to him in evil times. See Zep 3:18 Luke 22:28,29 .
