1 Samuel 20:5-7

Tomorrow is the new moon . The first day of the new moon was a joyful festival, its appearance being greeted with the sounding of trumpets, and celebrated by a burnt offering and a sin offering. It was, moreover, kept by Saul as a family festival, at which David, as his son-in-law, was expected to be present. As, moreover, David was to hide unto the third day at even , counting from the time when he was arranging his plans with Jonathan, it is plain that it was the rule to prolong the feasting unto the second day. When then Jonathan, convinced by David's pleading, had consented to aid him in his own way, they arrange that he shall absent himself from this festival, and remain during it hidden out of sight. In case Saul missed him and asked the reason of his absence, Jonathan was to offer as an excuse for him that he had earnestly requested leave to pay a hurried visit to Bethlehem, in order to be present at an annual festival: and if Saul took the excuse in good part it would be a sign that he had no malicious purposes towards David, whereas if he fell into a rage it would be a proof of a settled evil design. A yearly sacrifice for all the family. For all the mishpachah, i.e. not for all Jesse's household, but for all that subdivision of the tribe of Judah to which Jesse belonged; for a tribe was divided into families, and these again into fathers' houses ( Joshua 7:16 , Joshua 7:17 ). The occasion would thus be a grand one. In 1 Samuel 16:2 we have an instance of a special sacrifice at Bethlehem, but this feast of the mishpachah was held every year; and evidently before the temple was built at Jerusalem these local sacrifices were the rule. We may well believe that there was such a festival, and that the fictitious part of Jonathan's story was that David had been summoned to it.
