Now when Jesus heard these things
That he had kept all these commandments, and that ever since he was a child, and to that very time:
he said unto him, yet lackest thou one thing;
not but that he lacked many other things, and even every thing: for he had performed no one thing as it should be: but Christ said, partly in answer to his pert question, "what lack I yet?" and partly by an ironical concession, granting he had kept them all, as he had said, yet one thing was wanting; and chiefly with a view to mortify his pride and vanity:
sell all that thou hast, and distribute unto the poor, and thou
shalt have treasure in heaven, and come and follow me;
(See Gill on Matthew 19:21).
