這若翰穿著駱駝毛做的衣服，腰間束著皮帶，他的食物是蝗蟲和野蜜。

那時，耶路撒冷、全猶太，以及全約但河一帶的人都出來，到若翰那裡，承認自己的罪過，並在約但河受他的洗。他見到許多法利塞人和撒杜塞人，來受他的洗，就對他們說：

「毒蛇的種類！誰教你們逃避那即將來臨的憤怒？那麼，就結與悔改相稱的果實吧！你們自己不要想：我們有亞巴郎為父。我給你們說：天主能從這些石頭，給亞巴郎興起子孫來。斧刀已放在樹根上，凡不結好果子的樹，必被砍倒，投入火中。

「我固然用水洗你們，為使你們悔改；但在我以後，要來的那一位，比我更強，我連提他的鞋也不配，他要以聖神及火洗你們。他的簸箕已拿在手中，他要揚淨自己的禾場，將他的麥粒收入倉內，至於糠秕，卻要用不滅的火燒掉。」

When he saw many of the Pharisees and Sadducees coming to his baptism, he said to them, “You brood of vipers! Who warned you to flee from the coming wrath? Produce good fruit as evidence of your repentance. And do not presume to say to yourselves, ‘We have Abraham as our father.’ For I tell you, God can raise up children to Abraham from these stones. Even now the ax lies at the root of the trees. Therefore every tree that does not bear good fruit will be cut down and thrown into the fire. I am baptizing you with water, for repentance, but the one who is coming after me is mightier than I. I am not worthy to carry his sandals. He will baptize you with the Holy Spirit and fire. His winnowing fan is in his hand. He will clear his threshing floor and gather his wheat into his barn, but the chaff he will burn with unquenchable fire.”
