John Gill's Bible Commentary Ver. 9. If he be able to fight with me, and to kill me, then will we be your servants , etc.] For which it does not appear he had any commission or authority to say; nor did the Philistines think themselves obliged to abide by what he said, since, when he was slain, they did not yield themselves servants to the Israelites: but if I prevail against him, and kill him, then shall ye be our servants, and serve us ; to which terms also the Israelites did not consent; nor did David, who engaged with him, enter the fray on such conditions.
Matthew Henry Commentary
Verses 1-11 - Men so entirely depend upon God in all things, that when he withdraw his help, the most valiant and resolute cannot find their hearts of hands, as daily experience shows.
