6 And it cometh to pass, in their coming in, in David's returning from smiting the Philistine, that the women come out from all the cities of Israel to sing—also the dancers—to meet Saul the king, with tabrets, with joy, and with three-stringed instruments; 7 and the women answer—those playing, and say, 'Saul hath smitten among his thousands, And David among his myriads.' 8 And it is displeasing to Saul exceedingly, and this thing is evil in his eyes, and he saith, 'They have given to David myriads, and to me they have given the thousands, and more to him 'is' only the kingdom;' 9 and Saul is eyeing David from that day and thenceforth.
Matthew Henry's Commentary on 1 Samuel 18:6-9
Commentary on 1 Samuel 18:6-11
(Read 1 Samuel 18:6-11)
David's troubles not only immediately follow his triumphs, but arise from them; such is the vanity of that which seems greatest in this 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, and Saul, with his javelin in his hand, aiming to slay David; and observe 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.
