181 When David had finished speaking to Saul, the soul of Jonathan was bound to the soul of David, and Jonathan loved him as his own soul. 2 Saul took him that day and would not let him return to his father's house. 3 Then Jonathan made a covenant with David, because he loved him as his own soul. 4 Jonathan stripped himself of the robe that he was wearing, and gave it to David, and his armor, and even his sword and his bow and his belt. 5 David went out and was successful wherever Saul sent him; as a result, Saul set him over the army. And all the people, even the servants of Saul, approved.

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.
