Matthew Poole and continuators on 1 Samuel 16:1

AND the LORD said unto Samuel, How long wilt thou mourn for Saul , seeing I have rejected him from reigning over Israel ? Fill thine horn with oyl , and go, I will send thee to Jesse the Bethlehemite: for I have provided me a king among his sons.

And pray for his Restitution, which the following words imply that he did.

The manifestation of my peremptory Will, should make thee submit to my pleasure.

Which was used in the Inauguration of Kings, as chap. 10. 1. and 1 King. 1. 39. But here it is used in the Designation of a King, though David was not actually made King by it, but still remained a Subject, as is evident from chap. 24. 6. And the reason of this Anticipation was, partly, the comfort of Samuel, and other good men, against their great fears in case of Saul's Death, of which they expected every day to hear: and partly, the assurance of David's Title, which otherwise would have been very doubtful. For the prevention of which doubts, it was very meet, that the same Person and Prophet who had Anointed Saul, might now upon Gods rejection of Saul, Anoint David to succeed him upon his Death; and because Samuel was now not far from his Death, and was to die before Saul, it was fit that David's Anointing should be hastned and done before its proper time.

This Phrase is very Emphatical, and implies the difference between this and the former King. Saul was a King of the Peoples providing, he was the Product of their inordinate and sinful desires; they desired him for themselves, and for their own glory and safety, as they supposed: but this is a King of my own providing, one that I have spied out, one of that Tribe to which I have allotted the Kingdom, Gen. 49. 10. A King for me; not one to gratifie the Peoples desires, but to fulfil all my Will, as is said, Act. 13. 22. and to serve my Glory. Or, my King; the Hebrew Phrase, to me, or for me, being commonly used for the word mine.
