John Gill Commentary 1 Samuel 20:1

"And David fled from Naioth in Ramah, and came and said before Jonathan, What have I done? what is mine iniquity? and what is my sin before thy father, that he seeketh my life?" — 1 Samuel 20:1 (ASV)

And David fled from Naioth in Ramah
While Saul was prophesying, or lay in a trance there:

and came ;
to Gibeah, where Saul dwelt, and had his palace, and kept his court:

and said before Jonathan ;
whom he found there, and for whose sake he thither fled to have his advice, and to use his interest with his father, and be his friend at court:

what have I done? what [is] mine iniquity? and what [is] my sin before
your father, that he seeks my life ?
surely, as if he should say, I must have been guilty of some very great crime, and yet I am not sensible of it; can you tell me what it is that has so provoked your father, that nothing will satisfy him but the taking away of my life, which he seeks to do?
