I Samuel 18:21

The bond of friendship which Jonathan formed with David was so evidently the main point, that in Sa1 18:1 the writer commences with the love of Jonathan to David, and then after that proceeds in Sa1 18:2 to observe that Saul took David to himself from that day forward; whereas it is very evident that Saul told David, either at the time of his conversation with him or immediately afterwards, that he was henceforth to remain with him, i.e., in his service. "The soul of Jonathan bound itself (lit. chained itself; cf. Gen 44:30) to David's soul, and Jonathan loved him as his soul." The Chethibh ויּאהבו with the suffix ו attached to the imperfect is very rare, and hence the Keri ויּאהבהוּ (vid., Ewald, 249, b., and Olshausen, Gramm. p. 469). לשׁוּב, to return to his house, viz., to engage in his former occupation as shepherd.

In the course of the foregoing chapter we left David in triumph; now in this chapter we have, I. The improvement of his triumphs; he soon became, 1. Saul's constant attendant (Sa1 18:2). 2. Jonathan's covenant friend (Sa1 18:1, Sa1 18:3, Sa1 18:4). 3. The darling of his country (Sa1 18:5, Sa1 18:7, Sa1 18:16). II. The allays of his triumphs. This is the vanity that accompanies even a right work, that "for it a man is envied," Ecc 4:4. So David was by Saul. 1. He hated him, and sought to kill him himself (Sa1 18:8-11). 2. He feared him, and contrived how he might have some mischief done him (Sa1 18:12-17). He proposed to marry his daughter to him; but, [1.] cheated him of the eldest to provoke him (Sa1 18:19), and, [2.] Gave him the younger, upon conditions which would endanger his life (Sa1 18:20-25). But David performed his conditions bravely (Sa1 18:26, Sa1 18:27), and grew to be more and more esteemed (Sa1 18:28-30). Still David is rising, but (as all that aim at the crown of life must expect) he had a great deal of difficulty and opposition to grapple with.
