One would not thin that both the Old Testament and the New Testament are quite similar but, to my surprise they really are. In the Old Testament Moses goes up onto Mount Sinai to receive the ten commandments, while Jesus in the Old Testament goes up to a mountain to receive directions from God. In the Old Testament Moses is afraid that his people do not believe in the power of God and will try and come up the mountain. God proclaims that if anyone touches the mountain than they will die. In the New Testament God says if his people do anything of that sorts they will not be allowed in the kingdom of heaven. In both versions the people are hungry and tired and need a sign from God do that they can worship him.
Both the Old and New Testament are timeless pieces of literature that can be compared, or contrasted. Over the years many worshipers have done so. As you can see, there are most definetly more ways to compare the two.
