John Gill 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)

For I say to you
And it may be depended on as truth, and what will be found matter of fact:

that to every one that has, shall be given ;
greater and larger gifts, fitting him for greater usefulness: he that has gifts, and makes use of them, increases in them; they enlarge with their use, and become brighter, and he more useful. The Vulgate Latin version adds, "and he shall abound, or shall have abundance", as in (Matthew 25:29)

and from him that has not, even that he has shall be taken away
from him :
that is, that which he seemed to have, or thought he had, as in (Luke 8:18) for from him that has really nothing, nothing can be taken away: though the sense may be, that he that does not use the talent, or exercise the gift bestowed on him, but lays it up in a napkin, which is all one as if he had it not, even the gift itself shall be taken away from him; and as others receive no benefit by it, he shall receive no honour from it; (See Gill on Matthew 13:12) and (See Gill on Matthew 25:29).
