Contradiction with Isaiah 54:9
While Genesis 9:13 is about the covenant symbolized by the rainbow, Isaiah 54:9 states God’s promise not to be wrathful, rather than using a physical sign.
Isaiah 54:9: For this [is as] the waters of Noah unto me: for [as] I have sworn that the waters of Noah should no more go over the earth; so have I sworn that I would not be wroth with thee, nor rebuke thee.
Contradiction with Jeremiah 31:35-36
God's covenant in Genesis 9:13 involves the rainbow, whereas in Jeremiah, it is the fixed order of the universe that is cited as the basis of His promises.
Jeremiah 31:35-36: Thus saith the LORD, which giveth the sun for a light by day, [and] the ordinances of the moon and of the stars for a light by night, which divideth the sea when the waves thereof roar; The LORD of hosts [is] his name:
Contradiction with Hebrews 10:16
Genesis 9:13 involves a physical sign of the covenant, while Hebrews 10:16 emphasizes a covenant written in hearts.
Hebrews 10:16: This [is] the covenant that I will make with them after those days, saith the Lord, I will put my laws into their hearts, and in their minds will I write them;
Contradiction with Revelation 21:1
In Genesis 9:13, the promise is about never again flooding the earth. In Revelation 21:1, the current earth and heavens are replaced altogether, suggesting an end, contrasting with perpetual preservation.
Revelation 21:1: And I saw a new heaven and a new earth: for the first heaven and the first earth were passed away; and there was no more sea.
Paradox #1
Some people point out the potential inconsistency regarding rainbows in "Genesis 9:13" because it implies that rainbows appeared only after the flood. However, given the scientific explanation of rainbows as a natural phenomenon caused by sunlight interacting with water droplets, rainbows would logically exist as long as there is rain and sunlight—conditions that likely existed before the flood.
Paradox #2
The verse could conflict with scientific explanations about the natural phenomenon it describes. For example, it attributes a specific event to divine action while science explains it as a natural occurrence. This difference in interpretation can lead to contradiction.
