Genesis 1:26-27
6 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.
27 So God created man in his own image, in the image of God created he him; male and female created he them.
KJV
Genesis 1:26-27
26 Then God said, "Let us make man in our image, in our likeness, and let them rule over the fish of the sea and the birds of the air, over the livestock, over all the earth, and over all the creatures that move along the ground."
27 So God created man in his own image,
in the image of God he created him;
male and female he created them.
(from New International Version)
Well, when you compare verse for verse in both versions they agree. The plural pronoun in verse 26 as well as the plural nouns used for God in the OT indicate plurals of majesty, a practice adopted by kings who say "we" when referring to themselves. Verse 26 is also viewed as God addressing the heavenly host of angels or sons of God, which we are told in Job 38 shouted for joy when he laid the foundations of the earth.
