Therefore Saul removed him from him, and made him his captain over a thousand; and he went {f} out and came in before the people.

(f) Meaning he was captain over the people.

Wesley's Notes

18:13 Removed him from him - From his presence and court; which he did, because he feared lest David should find an opportunity to kill him, as he had designed to kill David; because his presence now made him more sad than ever his musick made him chearful: and principally, that hereby he might expose him to the greatest hazards.

Jamieson-Fausset-Brown Bible Commentary

1Sa 18:13-16. Fears Him for His Good Success.

13. Therefore Saul removed him from him-sent him away from the court, where the principal persons, including his own son, were spellbound with admiration of the young and pious warrior.

made him captain over a thousand-gave him a military commission, which was intended to be an honorable exile. But this post of duty served only to draw out before the public the extraordinary and varied qualities of his character, and to give him a stronger hold of the people's affections.

Matthew Henry's Concise Commentary

18:12-30 For a long time David was kept in continual apprehension of falling by the hand of Saul, yet he persevered in meek and respectful behaviour towards his persecutor. How uncommon is such prudence and discretion, especially under insults and provocations! Let us inquire if we imitate this part of the exemplary character before us. Are we behaving wisely in all our ways? Is there no sinful omission, no rashness of spirit, nothing wrong in our conduct? Opposition and perverseness in others, will not excuse wrong tempers in us, but should increase our care, and attention to the duties of our station. Consider Him that endured contradiction of sinners against himself, lest ye be weary and faint in your minds, Heb 12:3. If David magnified the honour of being son-in-law to king Saul, how should we magnify the honour of being sons to the King of kings!
