To the twelve tribes scattered among the nations: In the same way, the rich will fade away even while they go about their business.
bible vs james niv King
Saying it is "man's number" is to spread the number over all of humankind, as opposed to applying it to just one entity. Not only have they blatantly removed "this is the first commandment", but also the familiar "thou shalt" which introduces God's most important commands. Also their love, and their hatred, and their envy, is now perished; neither have they any more a portion for ever in any thing that is done under the sun.
The NIV leaves Christ out again. Grace and peace to you from God our Father.
