Si non crediderint, inquit, tibi, neque audierint sermonem signi prioris, credent verbo signi sequentis.
If they will not believe thee, saith he, nor hear the voice of the former sign, they will believe the word of the latter sign.
Si non crede, dic, ad te, neque audi sermone de signo priore, crede ad verbo de signo seque.
