Don't blindly listen to these people on youtube etc...
If you take a look at Mark 15:28 in the NIV, it's not there. HOWEVER, the NIV has footnotes and in the foot notes it clearly says ''some manuscripts left out, ''and the scripture was fufilled'' which says ''he was counted with the lawless ones.'' (Isaiah 53:12)
Just one example... to show you have to be careful what you believe, and that you should always check for yourself!
