Example #1
"And God said, Let us make man in our image, after our likeness: and let them have dominion over the fish of the sea, and over the fowl of the air, and over the cattle, and over all the earth, and over every creeping thing that creepeth upon the earth." Genesis 1:26
Note the plural "our image", "our likeness" Yet from other verses it is clear that man was created in Gods image and likeness (singular).
"So God created man in his own image, in the image of God created he him; male and female created he them." Genesis 1:27
"This is the book of the generations of Adam. In the day that God created man, in the likeness of God made he him;" Genesis 5:1
"Have we not all one father? hath not one God created us? why do we deal treacherously every man against his brother, by profaning the covenant of our fathers? " Malachi 2:10
Example #2
"And the LORD God said, Behold, the man is become as one of us, to know good and evil: and now, lest he put forth his hand, and take also of the tree of life, and eat, and live for ever:
Note the plural "us" with no idication of God speaking to others in the text.
"Therefore the LORD God sent him forth from the garden of Eden, to till the ground from whence he was taken." Genesis 1:23
Example #3
"And the LORD said, Behold, the people is one, and they have all one language; and this they begin to do: and now nothing will be restrained from them, which they have imagined to do. Go to, let us go down, and there confound their language, that they may not understand one another's speech." Genesis 11:6-7
Note the plural "us", also note only the LORD speaking (no mention of others) in verse 6 as well as verses 8-9.
"So the LORD scattered them abroad from thence upon the face of all the earth: and they left off to build the city." Genesis 11:8
"Therefore is the name of it called Babel; because the LORD did there confound the language of all the earth: and from thence did the LORD scatter them abroad upon the face of all the earth." Gensis 11:9
Example #4
"Then the LORD rained upon Sodom and upon Gomorrah brimstone and fire from the LORD out of heaven;" Genesis 19:24
"And he overthrew those cities, and all the plain, and all the inhabitants of the cities, and that which grew upon the ground." Genesis 19:25
Note the LORD raining brimstone and fire from the LORD out of heaven. The LORD had appeared in the form of a man to Abraham, and seems to have rained destruction from the LORD in heaven.
"I have overthrown some of you, as God overthrew Sodom and Gomorrah, and ye were as a firebrand plucked out of the burning: yet have ye not returned unto me, saith the LORD." Amos 4:11
Note: God is speaking and refers to "God" who overthrew Sodom and Gomorrah in the third person. (compare with Genesis 19:24 above).
