Revelation 4:3

4:3 And the one seated on it was like jasper and carnelian in appearance, and a rainbow looking like it was made of emerald encircled the throne.

Genesis 9:11-17

9:11 I confirm my covenant with you: Never again will all living things be wiped out by the waters of a flood; never again will a flood destroy the earth.”

9:12 And God said, “This is the guarantee of the covenant I am making with you and every living creature with you, a covenant for all subsequent generations: 9:13 I will place my rainbow in the clouds, and it will become a guarantee of the covenant between me and the earth. 9:14 Whenever I bring clouds over the earth and the rainbow appears in the clouds, 9:15 then I will remember my covenant with you and with all living creatures of all kinds. Never again will the waters become a flood and destroy all living things. 9:16 When the rainbow is in the clouds, I will notice it and remember the perpetual covenant between God and all living creatures of all kinds that are on the earth.”

9:17 So God said to Noah, “This is the guarantee of the covenant that I am confirming between me and all living things that are on the earth.”

Isaiah 54:9

54:9 “As far as I am concerned, this is like in Noah’s time,

when I vowed that the waters of Noah’s flood would never again cover the earth.

In the same way I have vowed that I will not be angry at you or shout at you.

Ezekiel 1:28

1:28 like the appearance of a rainbow in the clouds after the rain. This was the appearance of the surrounding brilliant light; it looked like the glory of the Lord. When I saw it, I threw myself face down, and I heard a voice speaking.
