I Samuel 21:2

David's Flight to Nob, and Thence to Gath - Sa1 21:1-15 After the information which David had received from Jonathan, nothing remained for him in order to save his life but immediate flight. He could not return to the prophets at Ramah, where he had been miraculously preserved from the first outbreak of Saul's wrath, because they could not ensure him permanent protection against the death with which he was threatened. He therefore fled first of all to Nob, to Ahimelech the high priest, to inquire the will of God through him concerning his future course (Sa1 22:10, Sa1 22:15), and induced him to give him bread and the sword of Goliath, also, under the pretext of having to perform a secret commission from the king with the greatest speed; for which Saul afterwards took fearful vengeance upon the priests at Nob when he was made acquainted with the affair through the treachery of Doeg (Sa1 21:1-9). David then fled to Gath to the Philistian king Achish; but here he was quickly recognised as the conqueror of Goliath, and obliged to feign insanity in order to save his life, and then to flee still farther (Sa1 21:10-15). The state of his mind at this time he poured out before God in the words of Psa 56:1-13; Psa 52:1-9, and 34.

David has now quite taken leave both of Saul's court and of his camp, has bidden farewell to his alter idem - his other self, the beloved Jonathan; and henceforward to the end of this book he is looked upon and treated as an outlaw and proclaimed a traitor. We still find him shifting from place to place for his own safety, and Saul pursuing him. His troubles are very particularly related in this and the following chapters, not only to be a key to the Psalms, but that he might be, as other prophets, an example to the saints in all ages, "of suffering affliction, and of patience," and especially that he might be a type of Christ, who, being anointed to the kingdom, humbled himself, and was therefore highly exalted. But the example of the suffering Jesus was a copy without a blot, that of David was not so; witness the records of this chapter, where we find David in his flight, I. Imposing upon Abimelech the priest, to get from him both victuals and arms (Sa1 21:1-9). II. Imposing upon Achish, king of Gath, by feigning himself mad (Sa1 21:10-15). Justly are troubles called temptations, for many are by them drawn into sin.

21:2 The king has sent me: David lied to conceal his outlaw status and to dispel Ahimelech’s worries.
