my master: Though they had booty enough, and this poor sick slave might have been carried on an ass or a camel, yet they inhumanely left him to perish; but, in the righteous providence of God, this cruelty was the occasion of their destruction; whilst David's kindness to a perishing stranger and slave was the means of his success, and proved the truest policy. Job 31:13-15; Pro 12:10; Jam 2:13
