Psalms 38:21

Forsake me not, O Lord ,.... Or continue not to forsake; for he seems to have been under divine desertion, and might be under apprehensions that God had utterly forsaken him; which he entreats he would not, though his friends had forsook him, and his own strength had failed and left him, Psalm 38:10 ;

O my God, be not far from me ; as to his gracious presence, and with respect to help and deliverance, otherwise God is not far from any of his creatures, being omnipresent.
