To eat meat ... - Fasting was a sign of the deepest mourning 2 Samuel 1:12. The fast lasted until the sun was set.

And when all the people came to cause David to eat meat while it was yet day,.... The custom was to bury in the daytime, and after the funeral was over to provide and send in food to the relations of the deceased, and come and eat with them; as was also the usage with the Greeks and Romans (w); See Gill on Jeremiah 16:5 and See Gill on Jeremiah 16:7; and kings themselves used to attend those feasts; for the Jews say (x),"when they cause him (the king) to eat, all the people sit upon the ground, and he sits upon the bed;''but in this case David refused to eat with them:

David sware, saying, so do God to me, and more also; may the greatest evils, and such as I care not to mention, befall me; and even more and worse than I can think of and express:

if I taste bread, or ought else, till the sun be down; perhaps the funeral was in the morning, as funerals with the Jews generally now are; for otherwise if it was now towards evening, his abstinence from food till that time would not have seemed so much, nor required much notice, and still less an oath.

(w) Vid. Kirchman. de Funer. Roman, l. 4. c. 5. & 6. (x) Misn. ut supra. (Sanhedrin, c. 2. sect. 3.) David de Pomis ut supra. (Lexic. fol. 119. 4.)

But David mourned so bitterly, that when all the people called upon him to take some food during the day, he declared with an oath that he would not taste bread or anything else before the setting of the sun. לחם הברות does not mean, as in 2 Samuel 13:5, to give to eat, on account of the expression "all the people," as it can hardly be imagined that all the people, i.e., all who were present, could have come to bring David food, but it signifies to make him eat, i.e., call upon him to eat; whilst it is left uncertain whether David was to eat with the people (cf. 2 Samuel 12:17), i.e., to take part in the funeral meal that was held after the burial, or whether the people simply urged him to take some food, for the purpose of soothing his own sorrow. אם כּי are to be taken separately: כּי, ὅτι, introducing the oath, and אם being the particle used in an oath: "if," i.e., assuredly not.

And when all the people came to cause David to eat {o} meat while it was yet day, David sware, saying, So do God to me, and more also, if I taste bread, or ought else, till the sun be down.

(o) According to their custom, which was to feast at burials.

3:22-39 Judgments are prepared for such scorners as Abner; but Joab, in what he did, acted wickedly. David laid Abner's murder deeply to heart, and in many ways expressed his detestation of it. The guilt of blood brings a curse upon families: if men do not avenge it, God will. It is a sad thing to die like a fool, as they do that any way shorten their own days, and those who make no provision for another world. Who would be fond of power, when a man may have the name of it, and must be accountable for it, yet is hampered in the use of it? David ought to have done his duty, and then trusted God with the issue. Carnal policy spared Joab. The Son of David may long delay, but never fails to punish impenitent sinners. He who now reigns upon the throne of David, has a kingdom of a nobler kind. Whatever He doeth, is noticed by all his willing people, and is pleasing to them.
