Psalms 109:10 Let his children be continually vagabonds, and beg: let them seek their bread also out of their desolate places. 11 Let the extortioner catch all that he hath; and let the strangers spoil his labor.
David himself was warned and instructed by God not to seek revenge upon Saul who hunted him like a wild beast for a long time, and David took the correction in stride, as he explained it to his soldiers, that they should not seek vengeance upon Saul. Furthermore, Saul had been very dead, a few years well, so David could not be referring to him.
And it’s not written anywhere in the Scriptures where David had such a bad beef with another person, for him to be uttering these withering curses, and asking God for revenge upon the person’s head. Therefore, it seems quite strange and odd, that here David would be found drooling over retaliation upon some unknown person, for he had already crossed that bridge, and thus, the question is: Who on earth could David be speaking of, in the following verses?
We must let the Scripture be its own interpreter, for when a Christocentric focus is employed in studying, it seems as if the verses in question have absolutely nothing to do with David. Thus, we will take several passages from Psalms 109, and we will permit the Bible to explain who David is referring to.
2nd Peter 1:19 We have also a more sure word of prophecy; whereunto you do well that you take heed, as unto a light that shineth in a dark place, until the day dawn, and the day star arise in your hearts: 20 Knowing this first, that no prophecy of the scripture is of any private interpretation. 21 For the prophecy came not in old time by the will of man: but holy men of God spoke as they were moved by the Holy Ghost.
May The Lord add His blessing to the study of His word. God bless!
