1 Samuel 20:41
And as soon as the lad was gone, David arose out of a place toward the south, and fell on his face to the ground, and bowed himself three times: and they kissed one another, and wept one with another, until David exceeded. And as soon as the lad was gone, David arose out of a place toward the south, and fell on his face to the ground, and bowed himself three times: and they kissed one another, and wept one with another, until David exceeded.
This parting belongs to the time after David defeated Goliath, when Saul kept David with him and would not allow him to return to his father's house. At that time Jonathan loved David as deeply as his own life and made a covenant to be united as brothers. In token of that covenant he stripped off his robe and gave it to David together with his other garments, his sword, his bow and his belt. At that same time David was entrusted with important responsibilities, yet he remained modest and won the affection of both the people and the royal household.
The verse shows the final meeting of David and Jonathan at an appointed place, where Jonathan reported that Saul was firmly resolved to kill David. There they embraced and wept bitterly together, falling on each other's neck in grief too intense to express. Saul's dark murderous hatred shadowed their lives and forced them to separate to go different ways.
The verse reveals a sacred bond of union in which Jonathan's heart was knit to David's, a friendship that remained unbroken until the deaths of Saul and Jonathan. That friendship was the Lord's doing, so that Jonathan could be the means of preserving David's life when Saul tried to kill him.
