181 After David had finished talking with Saul, Jonathan became one in spirit with David, and he loved him as himself.
181 And it came to pass, when he had made an end of speaking unto Saul, that the soul of Jonathan was knit with the soul of David, and Jonathan loved him as his own soul.
181 As soon as he had finished speaking to Saul, the soul of Jonathan was knit to the soul of David, and Jonathan loved him as his own soul.
181 By the time David had finished reporting to Saul, Jonathan was deeply impressed with David - an immediate bond was forged between them. He became totally committed to David. From that point on he would be David's number-one advocate and friend.
181 Now when he had finished speaking to Saul, the soul of Jonathan was knit to the soul of David, and Jonathan loved him as his own soul.
181 After David had finished talking with Saul, he met Jonathan, the king's son. There was an immediate bond between them, for Jonathan loved David.
Matthew Henry's Commentary on 1 Samuel 18:1
Commentary on 1 Samuel 18:1-5
(Read 1 Samuel 18:1-5)
The friendship of David and Jonathan was the effect of Divine grace, which produces in true believers one heart and one soul, and causes 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 weak to separate them. Those who love Christ as their own souls, will be willing to join themselves to him in an everlasting covenant. It was 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 up above measure.
