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 Psalms 52:1.
