Moses was speaking as from behind a veil they saw only the figures and patterns not the reality in Christ
“Seeing then that we have such hope, we use great plainness of speech: and not as Moses, which put a vail over his face, that the children of Israel could not stedfastly look to the end of that which is abolished: but their minds were blinded: for until this day remaineth the same vail untaken away in the reading of the old testament; ( the five Books of Moses ) which vail is done away in Christ. But even unto this day, when Moses is read, the vail is upon their heart.”
2 Corinthians 3:12-15 KJV
The ot we see is hidden in figures and shadows like we’re looking through Moses veil we only see shapes and shadows
