18 Jonathan said to him, "Tomorrow is the new moon; you will be missed, because your place will be empty. 19 On the day after tomorrow, you shall go a long way down; go to the place where you hid yourself earlier, and remain beside the stone there. 20 I will shoot three arrows to the side of it, as though I shot at a mark. 21 Then I will send the boy, saying, "Go, find the arrows.' If I say to the boy, "Look, the arrows are on this side of you, collect them,' then you are to come, for, as the Lord lives, it is safe for you and there is no danger. 22 But if I say to the young man, "Look, the arrows are beyond you,' then go; for the Lord has sent you away. 23 As for the matter about which you and I have spoken, the Lord is witness between you and me forever."
24 So David hid himself in the field. When the new moon came, the king sat at the feast to eat. 25 The king sat upon his seat, as at other times, upon the seat by the wall. Jonathan stood, while Abner sat by Saul's side; but David's place was empty. 26 Saul did not say anything that day; for he thought, "Something has befallen him; he is not clean, surely he is not clean." 27 But on the second day, the day after the new moon, David's place was empty. And Saul said to his son Jonathan, "Why has the son of Jesse not come to the feast, either yesterday or today?" 28 Jonathan answered Saul, "David earnestly asked leave of me to go to Bethlehem; 29 he said, "Let me go; for our family is holding a sacrifice in the city, and my brother has commanded me to be there. So now, if I have found favor in your sight, let me get away, and see my brothers.' For this reason he has not come to the king's table." 30 Then Saul's anger was kindled against Jonathan. He said to him, "You son of a perverse, rebellious woman! Do I not know that you have chosen the son of Jesse to your own shame, and to the shame of your mother's nakedness? 31 For as long as the son of Jesse lives upon the earth, neither you nor your kingdom shall be established. Now send and bring him to me, for he shall surely die." 32 Then Jonathan answered his father Saul, "Why should he be put to death? What has he done?" 33 But Saul threw his spear at him to strike him; so Jonathan knew that it was the decision of his father to put David to death. 34 Jonathan rose from the table in fierce anger and ate no food on the second day of the month, for he was grieved for David, and because his father had disgraced him.

Jonathan faithfully promises that he would let David know how he found his father affected towards him. It will be kindness to ourselves and to ours, to secure an interest in those whom God favours, and to make his friends ours. True friendship rests on a firm basis, and is able to silence ambition, self-love, and undue regard for others. But who can fully understand the love of Jesus, who gave himself as a sacrifice for rebellious, polluted sinners! how great then ought to be the force and effects of our love to him, to his cause, and his people!

(Read 1 Samuel 20:24-34)
None were more constant than David in attending holy duties; nor had he been absent, but self-preservation obliged him to withdraw. In great peril present opportunities for Divine ordinances may be waved. But it is bad for us, except in case of necessity, to omit any opportunity of statedly attending on them. Jonathan did wisely and well for himself and family, to secure an interest in David, yet for this he is blamed. It is good to take God's people for our people. It will prove to our advantage at last, however it may now be thought against our interest. Saul was outrageous. What savage beasts, and worse, does anger make men!
