And he that saw {it} bare record, and his record is true: and he knoweth that he saith true, that ye might believe.
He who has seen has testified, and his testimony is true. He knows that he tells the truth, that you may believe.

kai o eōrakōs memartyrēken kai alēthinē aytoy estin ē martyria kakeinos oiden oti alēthē legei ina ymeis pisteysēte
