Today we read in John 5:31-47 how Jesus defended His testimony.
In Genesis 9 God established His covenant with Noah (The Noahic Covenant), and as a sign He established the rainbow in the sky. Noah planted a vineyard, got drunk and exposed his nakedness. This lead to “the curse of Ham,” which gave the excuse that the black race was destined for servanthood and slavery. It was in reality the curse of Canaan, the original inhabitants of the yet to be promised land. Ponder that!
Genesis 10 is a genealogy of the descendants of Noah. It describes how the earth was repopulated. This is quite interesting to see how the different tribes developed.
When Jesus defended his testimony the Scriptures were already written and pointed to the coming Messiah. In most of the prophesies Messiah is described as a conqueror. He will reestablish Israel in all its glory, and the prophesies of the suffering messiah of divine origin were ignored as being inconsistent with the purpose and destiny of Israel. This is why Jesus testimony was vehemently opposed.
In Noah’s time on the other hand none of the Scriptures had been written, so God in His grace gave Noah the covenant He would never again destroy mankind with a flood, and He sealed it with the sign of the rainbow as a remembrance. After the deluge weather patterns changed and thunderstorms became common in season. In spite of this it didn’t take long for Noah to sin and get drunk, and from that story we get “the curse of Ham” which really was the curse of Canaan.
