Exo 34:1 And the LORD said unto Moses, Hew thee two tables of stone like unto the first: and I will write upon these tables the words that were in the first tables, which thou brakest. 2 And be ready in the morning, and come up in the morning unto mount Sinai, and present thyself there to me in the top of the mount. 3 And no man shall come up with thee, neither let any man be seen throughout all the mount; neither let the flocks nor herds feed before that mount.
Exo 34:4 And he hewed two tables of stone like unto the first; and Moses rose up early in the morning, and went up unto mount Sinai, as the LORD had commanded him, and took in his hand the two tables of stone.
Eze 11:19 And I will give them one heart, and I will put a new spirit within you; and I will take the stony heart out of their flesh, and will give them an heart of flesh:
Have you ever wondered why Moses had to cut the stones himself for God to re-write the Ten Commandments? God had done the whole job the first time, why didn't He do it all again? Well, I have wondered this, and I asked God why. This is what He showed me: The stone tablets represent our hearts. They have become hard, like stone, through sin. And the only way we can become right with Him is if we bring our hard hearts to Him in humility, admitting our sin. It is hard work, like chiseling stone, but it is the only way. Then, when we turn to Him in this way, He graciously gives us hearts of flesh instead of stone, and writes His law on our hearts, as He promised He would.
