'Ignorantly' in the Bible

And whoever eats some of its meat shall wash his clothes, and be unclean until evening; also whoever picks up its carcass shall wash his clothes, and be unclean until the evening.

But [in fact] He has borne our griefs,And He has carried our sorrows and pains;Yet we [ignorantly] assumed that He was stricken,Struck down by God and degraded and humiliated [by Him].
