In a short post, Peter Leithart notes. “The Hebrew word for “marred” occurs in only two places in the Old Testament: It describes the Suffering Servant (Isaiah 52:14) and it is used to refer to disfigurements that disqualify a descendant of Aaron from being priest (Leviticus 22:25). The connection doesn’t seem fortuitous.”
But in Isaiah 53, we see that God does accept His Son. Leithart concludes,
It means that in the Servant we have a priesthood and a sacrificial system different from the Mosaic system and the Aaronic priesthood.
The vindication of the Servant’s offering by His resurrection announces a new order of things. More than announce: It creates a new order of things.
