Psalm 34:9

O fear the Lord, ye his saints
Who are sanctified by his Spirit, and so are openly and manifestly his; these are exhorted to fear the Lord with reverence and godly fear; and great reason there is why they should fear him, since he is King of saints, and fear is due to him from them; and seeing they have received many instances of grace and goodness from him, and therefore should fear him for his goodness's sake; and besides they, and they only, know him, and have the grace of fear in them, and so only can exercise it on him;

for [there is] no want to them that fear him;
not in spirituals, since so much goodness is laid up for them; the heart of God is towards them, his secret is with them, his eye is upon them, and the sun of righteousness arises on them; and both grace and glory are given to them; nor in temporals, since godliness, or the fear of God, has the promise of this life, as well as of that which is to come.
