Surely he took up our pain and bore our suffering, yet we considered him punished by God, stricken by him, and afflicted. (NIV)

Surely He has borne our griefs (sicknesses, weaknesses, and distresses) and carried our sorrows and pains [of punishment], yet we [ignorantly] considered Him stricken, smitten, and afflicted by God [as if with leprosy]. [Matt. 8:17.] (AMP)

Surely he hath borne our griefs, and carried our sorrows: yet we did esteem him stricken, smitten of God, and afflicted. (KJV)
