Psalms 119:152

Concerning thy testimonies -In regard to all that thou hast testified to as true and best. Every command of God is in fact a testimony of his as to what is right; every promise is a testimony of his own purpose in regard to mankind. I have known of old -The word used here is a noun, and means properly, “the front,” what is “before;” then, the East; then, what pertains to olden time or ancient days - “before” the present. The meaning here is, that he had known this “before” what had now occurred; it was not a new thing - a new experience. It was deeply impressed on his mind as the result of all his reflection and observation.
