An interesting difference in the KJV vs. NIV is in Genesis 1:28. KJV says "replenish the earth, and subdue it."
The NIV says "fill the earth and subdue it."
The word replenish caught my eye last night reading. Replenish is kind of a weird term here, is it not? It implies restoring something, and in this case something that was just created. I just find that odd.
