I was wondering if anybody in this group is familiar with the various covenants that the Hebrew Torah (the Pentateuch) speaks of. These covenants are Israel's covenant, Abraham's covenant and Noah's covenant. These covenants still apply today, and Noah's covenant applies to all mankind apart from the children of Israel. The sign of Noah's covenant is the rainbow.
If anybody is curious about these covenants, feel free to take a look at the following website:
