SEV Biblia, Chapter 18:2
Y Saúl le tomó aquel día, y no le dejó volver a casa de su padre.
John Gill's Bible Commentary
Ver. 2. And Saul took him that day , etc.] Not only into his favour, and into his service, but into his court; even on that very day he slew the Philistine, or however as soon as it could be done: and would let him go no more home to his father’s house ; as he used to do before; when he only served as a musician to him, then he was only at court when Saul was in a melancholy disposition, and wanted him, and so was going and returning, and in the intervals kept his father’s sheep, ( Samuel 17:15); but now he would not suffer him to attend such business any longer, since he was not only to become a courtier, and be made a prince or noble, but to marry his daughter, according to the declaration he had made, with respect to any man that should kill Goliath.
Matthew Henry Commentary
Verses 1-5 - The friendship of David and Jonathan was the effect of Divine grace which produces in true believers one heart and one soul, and cause them to love each other. This union of souls is from partaking in the Spirit of Christ. Where God unites hearts, carnal matters are too wea to separate them. Those who love Christ as their own souls, will be willing to join themselves to him in an everlasting covenant. It wa certainly a great proof of the power of God's grace in David, that he was able to bear all this respect and honour, without being lifted u above measure.
