Jesus renames Simon (Jewish name Simeon), Simon is how it is written in the greek, but not so in the hebrew. Jesus gives him the name Peter (which was Petros in the greek). Now comes the detective work. What does the name of Simeon mean?
In Jacob’s final blessing to his sons on his deathbed, in Genesis 49, he finally condemns the actions of Simeon, saying: “their swords are weapons of violence. Let me not enter their council, let me not join their assembly, for they have killed men in their anger and hamstrung oxen as they pleased. Cursed by their anger, so fierce, and their fury, so cruel! I will scatter them in Jacob and disperse them in Israel” (5-7). Because of this deed, Simeon is to be scattered, and his descendants will have no land of their own.
At the beginning of the exodus, the Simeonites number about 59,300. By the time they are ready to enter the Promised Land, their number has fallen to 22,200. When the land is apportioned in the Book of Joshua, they are only given a few cities. The tribe of Simeon only survives a few generations and is ultimately absorbed by the tribe of Judah, thereby effectively erasing any trace of Simeon. The Simeonites are mentioned in I Chronicles, but for all practical purposes, they are scattered and never own their own portion of land.
Jesus renames Simon and by doing so, gives him a new destiny and a new character, his curse in removed and He is now to be solid and immovable like a rock.
Now lets look at the greek. In the greek peter is petros, or a stone which also means a rock, but petra which also sounds like petros is a solid and immovable rock these two words are retained in the latin, where petros is translated as saxum and petra is translated as rupes, or scopulus.
Thou art Peter (petros) and upon this rock (petra), I will build my church.
