A.T. Robertson Commentary Luke 19:26

"I say unto you, that unto every one that hath shall be given; but from him that hath not, even that which he hath shall be taken away from him." — Luke 19:26 (ASV)

That hath not (του μη εχοντος). The present tense of εχω here, that keeps on not having, probably approaches the idea of acquiring or getting, the one who keeps on not acquiring. This is the law of nature and of grace.
