Matthew 8:21 - Ellicott's Commentary On The Whole Bible

Suffer me first to go and bury my father. — A curious tradition, preserved by Clement of Alexandria, says that the disciple who came with this request was Philip. Nothing in the Gospel history, however, suggests this. Philip had been called before, and had obeyed the call (John 1:43). All that we can say is that it may have been so, and that he may at this stage of his spiritual growth have shrunk from the fresh activity of actual service in the work of evangelising. The form of the petition may mean either (1) that his father was then actually dead, and that the disciple asked leave to remain and pay the last honours to his remains, or (2) that he asked to remain with his father till his death. The latter seems by far the most probable. In the East burial followed so immediately on death that the former would hardly have involved more than the delay of a few hours. In the latter case the request was, in fact, a plea for indefinite postponement. This at least fits in best with the apparent severity of our Lord’s answer.
