Isa. 9:6 is one of the best-loved verses we read at Christmas. I looked at it this morning in both the Hebrew and the Greek. Sometimes the Greek of the LXX is extremely literal. It reads a lot like an interlinear of the Hebrew text. Not so here.
"For a child was born to us. A son, also, was given to us, whose rule is upon his shoulder. And his name is called Angel of the great counsel. For I will bring peace upon the rulers and health to him."
