Psalms 95:O come, let us sing unto the Lord: let us make a joyful noise to the rock of our salvation. 2 Let us come before his presence with thanksgiving, and make a joyful noise unto him with psalms.
Christ, as The Rock is also figuratively referred to in the scriptures, for He is written of by all writers of the Old Testament, and the New Testament, even though at times those representations may not be readily apparent to the cursory reader. Moses, and David wrote extensively of The Rock, and in other books of the Bible Christ is represented by the same symbol.
For instance, we find in the New Testament, Christ stating emphatically that Moses wrote of Him, yet, when the scriptures are studied closely, Christ is seen mostly in shadows and symbols, and for this reason, many persons who read the Bible, may be entirely missing the point, whenever Christ is to be found in otherwise dark sentences.
When Moses smote the rock, and the water gushed forth, it was Christ who was being prefigured, as He would be smitten on the cross for our sins, and out of His side would flow not only blood, but water, as per the soldier thrusting his spear into His side. But to an individual who was only focused on the human agent, it was Moses who stole the show. Hence the reason why in the book of John, the Jews referred to Moses as the one who had supplied the manna in the desert.
John 5:46 For had ye believed Moses, ye would have believed me; for he wrote of me. 47 But if ye believe not his writings, how shall ye believe my words?
May The Lord add His blessing to the study of His word. God bless!
