The characteristic generosity of David's disposition breaks out in these words. He never forgot a friend. (Compare 2 Samuel 1:26; 2 Samuel 9:1, etc.) David acknowledges that Saul's enmity against Abiathar is the consequence of his enmity against himself, and therefore David makes common cause with him.

He that seeketh my life seeketh thy life - The enmity of Saul is directed against thee as well as against me, and thou canst have no safety but in being closely attached to me; and I will defend thee even at the risk of my own life. This he was bound in duty and conscience to do.

Abide thou with me, fear not,.... He appeared to be in a fright; which is not to be wondered at, as not knowing what to do, and where to go and provide for his safety; when, to allay his fears, and make him easy, David invites and encourages him to stay with him, and not be afraid of Saul, nor any other:

for he that seeketh my life seeketh thy life; or, as Kimchi observes, it may be interpreted, "my life he seeks who seeks thy life"; we are in the same circumstances, and have the same common enemy, and therefore it is best and safest to be together; as the Targum,"he that seeks to kill me seeks to kill thee;''and as Jarchi adds, he that loves me will love thee, and he that keeps my life will keep thine:

but with me thou shalt be in safeguard; intimating, that he would be as careful of him as of himself; and that for this reason, as Ben Gersom suggests, because he brought the ephod with the Urim and Thummim with him, by which he could inquire of God for him; but this was the thing David was confident of, that God would preserve him, and raise him to the kingdom, and therefore Abiathar might be sure of safety with him: at this time he penned the fifty second psalm, which shows the frame of spirit he was now in; see Psalm 52:1.

Abide thou with me, fear not: for he that seeketh my life seeketh thy life: but with me thou shalt be in safeguard.

22:20-23 David greatly lamented the calamity. It is great trouble to a good man to find himself any way the cause of evil to others. He must have been much pained, when he considered that his falsehood was one cause of this fatal event. David speaks with assurance of his own safety, and promises that Abiathar should have his protection. With the Son of David, all who are his may be sure they shall be in safeguard, Ps 91:1. In the hurry and distraction David was continually in, he found time for communion with God, and found comfort in it.
