1 Samuel 18:3 Meaning and Commentary

1 Samuel 18:3

Then Jonathan and David made a covenant
A covenant of friendship; entered into a solemn agreement to keep up and maintain a cordial respect to each other, and to support each other's interest both in life and after death, whoever was the survivor; and in consequence of this David had a friend at court, when Saul fell out with him, and who pleaded his cause, and discovered his father's plots, and was the means of preserving David's life:

because he loved him as his own soul;
so that this covenant was not founded in mere words, but in sincere and cordial affection, and was lasting and inviolable.

1 Samuel 18:3 In-Context

1 Now after David's talk with Saul was ended, the soul of Jonathan was joined with the soul of David, and David became as dear to him as his very life.

2 And that day Saul took David and would not let him go back to his father's house.

3 Then Jonathan and David made an agreement together, because of Jonathan's love for David.

4 And Jonathan took off the robe he had on and gave it to David, with all his military dress, even to his sword and his bow and the band round his body.

5 And David went wherever Saul sent him, and did wisely: and Saul put him at the head of his men of war, and this was pleasing to all the people as well as to Saul's servants.
