ISB ~ Mark 2 v7

it is blasphemy!:The scribes are incensed that Jesus claims for himself a prerogative that belongs only to God: the power to remit sins (Ps 103:3; Is 43:25; CCC 1441). They have misjudged the matter as blasphemy, which was a capital crime in ancient Israel (Lev 24:16). Note that Jesus manifests his divinity both by absolving the man’s sins and by exposing the unspoken disapproval of his critics (2:8).
