18 Then Jonathan said to him, “Tomorrow is the new moon: and you will be missed, because your seat will be empty. 19 When you have stayed three days, you shall go down quickly, and come to the place where you did hide yourself when the business was in hand, and shall remain by the stone Ezel. 20 I will shoot three arrows on its side, as though I shot at a mark. 21 Behold, I will send the boy, saying, ‘Go, find the arrows!’ If I tell the boy, ‘Behold, the arrows are on this side of you. Take them;’ then come; for there is peace to you and no hurt, as Yahweh lives. 22 But if I say this to the boy, ‘Behold, the arrows are beyond you;’ then go your way; for Yahweh has sent you away. 23 Concerning the matter which you and I have spoken of, behold, Yahweh is between you and me forever.”
24 So David hid himself in the field: and when the new moon was come, the king sat him down to eat food. 25 The king sat on his seat, as at other times, even on the seat by the wall; and Jonathan stood up, and Abner sat by Saul’s side: but David’s place was empty. 26 Nevertheless Saul didn’t say anything that day: for he thought, “Something has happened to him. He is not clean. Surely he is not clean.” 27 It happened on the next day after the new moon, the second day, that David’s place was empty. Saul said to Jonathan his son, “Why doesn’t the son of Jesse come to eat, neither yesterday, nor today?” 28 Jonathan answered Saul, “David earnestly asked leave of me to go to Bethlehem. 29 He said, ‘Please let me go, for our family has a sacrifice in the city. My brother has commanded me to be there. Now, if I have found favor in your eyes, let me get away, please, and see my brothers.’ Therefore he has not come to the king’s table.” 30 Then Saul’s anger was kindled against Jonathan, and he said to him, “You son of a perverse rebellious woman, don’t I 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 on the earth, you shall not be established, nor your kingdom. Therefore now send and bring him to me, for he shall surely die!” 32 Jonathan answered Saul his father, and said to him, “Why should he be put to death? What has he done?” 33 Saul cast his spear at him to strike him. By this Jonathan knew that his father was determined to put David to death. 34 So Jonathan arose from the table in fierce anger, and ate no food the second day of the month; for he was grieved for David, because his father had done him shame.

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!
