SEV Biblia, Chapter 18:9
Y desde aquel día Saúl miró de través a David.
John Gill's Bible Commentary
Ver. 9. And Saul eyed David from that day and forward .] Instead of looking pleasantly, and with a smile, upon him, as a courtier and favourite, he was justly entitled to by his gallant behaviour, he looked at him with a sour, ill natured look; he looked at him with an evil, spiteful, malicious, and envious eye; or he diligently watched and observed all his motions and actions, whether they tended to disloyalty and treason, to dethrone him, and take the kingdom to himself, which he was suspicious of; he laid wait for him, as the Targum, and laid snares too, as the following history shows.
Matthew Henry Commentary
Verses 6-11 - David's troubles not only immediately follow his triumphs, but aris from them; such is the vanity of that which seems greatest in thi world. It is a sign that the Spirit of God is departed from men, if like Saul, they are peevish, envious, suspicious, and ill-natured Compare David, with his harp in his hand, aiming to serve Saul, an Saul, with his javelin in his hand, aiming to slay David; and observ the sweetness and usefulness of God's persecuted people, and the barbarity of their persecutors. But David's safety must be ascribed to God's providence.
