I Samuel 20:18

David, having several times narrowly escaped Saul's fury, begins to consider at last whether it may not be necessary for him to retire into the country and to take up arms in his own defence. But he will not do so daring a thing without consulting his faithful friend Jonathan; how he did this, and what passed between them, we have an account in this chapter, where we have as surprising instances of supernatural love as we had in the chapter before of unnatural hatred. I. David complains to Jonathan of his present distress, and engages him to be his friend (Sa1 20:1-8). II. Jonathan faithfully promises to get and give him intelligence how his father stood affected to him, and renews the covenant of friendship with him (Sa1 20:9-23). III. Jonathan, upon trial, finds, to his grief, that his father was implacably enraged against David (Sa1 20:24-34). IV. He gives David notice of this, according to the appointment between them (Sa1 20:35-42).

20:18-22 Jonathan’s ruse would allow David to get the message even if there could be no face-to-face meeting; the boy’s presence would allay suspicion and provide Jonathan an alibi for going to the field. As it happened, no one but the boy accompanied Jonathan to the field, so when the boy left, David was able to speak with Jonathan face to face (20:40-42).
