20:1-10 The trials David met with, prepared him for future advancement. Thus the Lord deals with those whom he prepares unto glory. He does not put them into immediate possession of the kingdom, but leads them to it through much tribulation, which he makes the means of fitting them for it. Let them not murmur at his gracious appointment, nor distrust his care; but let them look forward with joyful expectation to the crown which is laid up for them. Sometimes it appears to us that there is but a step between us and death; at all times it may be so, and we should prepare for the event. But though dangers appear most threatening, we cannot die till the purpose of God concerning us is accomplished; nor till we have served our generation according to his will, if we are believers. Jonathan generously offers David his services. This is true friendship. Thus Christ testifies his love to us, Ask, and it shall be done for you; and we must testify our love to him, by keeping his commandments.

5. David said unto Jonathan, Behold, to-morrow the new moon, and I should not fail to sit with the king at meat—The beginning of a new month or moon was always celebrated by special sacrifices, followed by feasting, at which the head of a family expected all its members to be present. David, both as the king's son-in-law and a distinguished courtier, dined on such occasions at the royal table, and from its being generally known that David had returned to Gibeah, his presence in the palace would be naturally expected. This occasion was chosen by the two friends for testing the king's state of feeling. As a suitable pretext for David's absence, it was arranged that he should visit his family at Beth-lehem, and thus create an opportunity of ascertaining how his non-appearance would be viewed. The time and place were fixed for Jonathan reporting to David; but as circumstances might render another interview unsafe, it was deemed expedient to communicate by a concerted signal.
