Blessed is your discernment, and blessed are you, because today you kept me from bloodshed and from avenging myself by my own hand.
KJV
And blessed [be] thy advice, and blessed [be] thou, which hast kept me this day from coming to [shed] blood, and from avenging myself with mine own hand.
ASV
and blessed be thy discretion, and blessed be thou, that hast kept me this day from bloodguiltiness, and from avenging myself with mine own hand.
