Stablish thy word unto thy servant, who is devoted to thy fear.
Stablish thy word unto thy servants, who is devoted to thy fear - or, 'thy Word which belongs to thy fearers;' namely, to them who fear thee (Hengstenberg). I prefer the English version (cf. Psalms 119:76; Psalms 119:173; 2 Samuel 7:25). Give the additional grace which thou promisest to one who uses the grace already given, and with reverential "fear" asks from his heart for more (Muis). Also "stablish thy word" of promise respecting the ultimate permanence of David's seed and kingdom (1 Kings 2:4; 1 Kings 8:25).
