John Gill Commentary Psalms 119:38

"Confirm unto thy servant thy word, Which [is in order] unto the fear of thee." — Psalms 119:38 (ASV)

Establish your word to your servant
Either God's word of promise, which never fails, is firm and stable in Christ; and the sense is, that God would assure him of the fulfilment of it, and give him a strong faith and firm belief of it; for otherwise the word of the Lord cannot be surer or more stable than it is: or else the word of his grace; and then the sense is, that he might be established in it, and the truths of it, and be established by it; for the word is a means of establishment, and a good thing it is to have the heart established with grace, with the doctrine of grace, (Hebrews 13:9);

who [is devoted] to your fear ;
who served the Lord with reverence and godly fear; who feared the Lord and his goodness; that grace being a reigning one in his heart, and ever before his eyes. Or, "which is to your fear" ^F4 ; that is, which word is to your fear; which leads to it, and has a tendency to promote and increase it; and so is a commendation of the word of God from this effect of it.
