So shall I have wherewith to answer him that reproacheth me,
&c.] Saying there is no help and salvation for him in God; asking where is his God, in whom he trusted? and where is the promise of salvation, on which he depended? To which an easy and ready answer might be given, when the mercies and salvation of God came unto him, and he clearly appeared to be interested in them; see ( Psalms 3:2 ) ( 42:10 ) ;
for I trust in thy word:
in Christ the essential Word, the object of trust and confidence; or in the written word, it being divinely inspired and dictated by the Spirit of God, and so to be depended on as true and faithful; or rather God's word of promise concerning mercy, grace, and salvation, which God that has made is faithful and able to perform, as may be believed.
