The new moon, or beginning of each month, was celebrated with especial sacrifices and blowing of trumpets (marginal references.) The feast was kept with great solemnity as "a day of gladness," and we may presume that the "peace offerings" offered on the occasion furnished the tables of those that offered.

To-morrow is the new moon - The months of the Hebrews were lunar months, and they reckoned from new moon to new moon. And as their other feasts, particularly the passover, were reckoned according to this, they were very scrupulous in observing the first appearance of each new moon. On these new moons they offered sacrifices, and had a feast; as we learn from Numbers 10:10; Numbers 28:11. And we may suppose that the families, on such occasions, sacrificed and feasted together. To this David seems to refer; but the gathering together all the families of a whole tribe seems to have taken place only once in the year. There is a yearly sacrifice there for all the family, 1 Samuel 20:6.

And David said unto Jonathan,.... Moved that the following method might be taken as a trial of the disposition of Saul's mind towards David:

behold, tomorrow is the new moon; the first day of the month, which was kept solemnly with burnt offerings and peace offerings, see Numbers 10:10. Some say (r) this feast was not kept for the new moon, but because it was the day of the feast of trumpets or the first day of the new year, which fell together on that day; the calends, or first day of the month, was with the Heathens sacred to deity (s), in imitation of the Jews:

and I should not fail to sit with the king at meat; it had been usual for him at such a time to sit at table with the king; next to him, as Jarchi interprets it, either as his son-in-law, or as one of his princes; the custom being for the king, and his family and nobles, to eat together on that day upon the peace offerings; and it was the duty of David to attend at that time, and it might be expected he would:

but let me go; he asked leave of Jonathan, who had power in his father's absence to grant it, he not being yet returned from Naioth:

that I may hide myself in the fields, unto the third day at even; or until the time of the evening of the third day, as the Targum, which was the evening of the second day of the month; for that was the third from that evening they were discoursing together, as Ben Gersom observes; the fields he proposed to hide himself in were near to Gibeah, and he doubtless meant some cave in those fields, where he might be, and not be seen by men; though it cannot be thought that he remained, or proposed to remain, in such a place during that time, where he would be in want of food, but that he would abide incognito among his friends somewhere or another, until the festival was over.

And David said unto Jonathan, Behold, to morrow is the {c} new moon, and I should not fail to sit with the king at meat: but let me go, that I may hide myself in the field unto the third day at even.

(c) At what time there would be a solemn sacrifice, Nu 28:11, to which they added peace offerings and feasts.

20:5 To the third day - That is, unto the next day, but one after the new moon. His meaning is not, that he would hide himself in any certain place all the three days, but that he would secure himself either at Bethlehem with his friends, or in any other place 'till the third day.

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.

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.
