All took their assigned places at the feast, the king coming in last apparently with his back to the wall in the place of honour, and Abner, the captain of his army, next to him, and possibly Jonathan on his other side. Jonathan arose, probably out of deference to his father, but then sat down again (verse 34).
We see the strength of true friendship. Not even a threat to life can dislodge the love that Jonathan has for David. Jonathan will continue to do what is right, no matter how much pressure is put on him. True love is not easily corrupted or intimidated; it has within it a strong sense of what is right. When forced to make choices, it makes them without hesitation.
The passage teaches us the danger of harbouring anger. This is Saul who had already repented of his murderous intent towards David once (1 Samuel 19:1-6), but his repentance has been shallow and he had not truly put his sin to death, so that in a short time it reasserted itself in his heart. Insincere repentance is an act of self-deception. We may even think what we have done is real, because we want to believe we have power over our own hearts. This is a sin which must be deeply repented of when we come to the Lord, and we must ask God to search our hearts and show us what is in them, because of our self-blindness. It is not something that can be allowed to continue in any form: ‘Let all bitterness, and wrath, and anger, and clamour, and evil speaking, be put away from you, with all malice’ (Ephesians 4:31). Behind anger is pride, and Saul who had been so small in his own eyes to begin with, is now so sensitive to any implied hurt or criticism that he loses all control of himself.
One can't help noting the futility of empty worship. It does not change us. It doesn't take hold of our lives; it doesn't put within us any better intentions. Only conversion to Jesus Christ makes a difference to the life. Even as Christian people, if we engage in shallow and unthinking worship with minds wandering, it won’t help us, it won't strengthen us. Saul may have been wholly involved and engaged in it at the time, so that people around him were astonished, but it amounted to nothing, and immediately gave way to murderous instincts.
