Ubuninahazwa bw’Umukama buzokwihonekeza, kandi kandi nta wuzosigara atabubonye
Humurize, humurize igihugu canje. Nimusubirize umutima mu nda Abanyayeruzalemu. Babwire muti : « Igikorwa canyu kirarangiye, igicumuro canyu carishuwe. Umukama yarabahanye ikirenga kabiri ku bicumuro vyanyu. » Ijwi risemerera riti : « Nimuharurire Umukama inzira mu gahinga, muharurire Imana yacu inzira igororotse mw’idonzi. Umubande wose ufurirwe, umusozi n’umutumba wose biringanizwe, ahari imanga hose hongere hasaswe, na ho ahaduga nk’uruti rw’icumu haringanizwe. Niho ubuninahazwa bw’Umukama buzokwihonekeza, kandi nta wuzosigara atabubonye, kuko Umukama yarivumereye. »

Na yo impera yiwe yamutanze imbere. Azoragira ubusho bwiwe nk’umwungere, azoterurira imyagazi mu maboko yiwe ayifumbatire ku gikiriza ciwe, intama zonsa na zo azozibungabunga.

Icit. : Ninahaza Umukama, se mushaha wanje
kuko ari mukuru cane.
Ninahaza Umukama, se mushaha wanje !
Mukama Mana yanie, uri mukuru cane !
Ubukuru n’ubwiza bibarizwa iwawe,
umuco uwikwiza uk’igikwemu.
Umukama yashinze umurwa wiwe kw’ijuru (y’amazi yo hejuru),
ibicu bikamubera inderuzo
agendera ku mababa y’umuyaga.
Imiyaga ayigira irtumwa ziwe,
amasase y’umuriro akayagira abasuku.
Ivyiza wakoze ni isinzi, Mukama,
kandi wabigiranye ubuhinga,
isi ihinda itunga ryawe.
Raba ikiyaga amahero, ibikoko indiri n’indiri
bikivogeramwo, ibinini n’ibitoyi.
Bose barindiriye
ko wobakora mu minwe igihe kigeze ;
urabibaha, bakavyakiriza yompi,
uragaranzura ibiganza, bagahazwa n’ivyiza vyawe.
Winyegeje, igihumura gica kibica,
baca barumara bagasubira mw’ivu.
Ubasubije agatima, ng’abo barakomeye
kandi ugaca uhindura isi.

INKURU NZIZA
Aleluya, Aleluya.
Yohani yavuze ati : « Haje uwundusha ububasha ;
ni we azobabatiza muri Mutima Mweranda n’umuriro. »
Aleluya.
Ivyo dusoma mu Nkuru nziza ya Yezu Kristu nk’uko yashikirijwe na Luka (3, 15-16. 21-22)
Yezu amaze kubatizwa igihe yariko arasenga, ijuru ririyugurura 
Abantu baje kwa Yohani ngo babatizwe bari biteze ikintu kandi baguma bibaza mu mitima yabo ko Yohani atari we Kristu. Yohani araheza ababwira hose ati : « Jewe mbatirisha amazi, ariko haje uwundusha ububasha sinkwiye n’ugupfundurura ibirato vyiwe, azobabatiza muri Mutima Mweranda n’umuriro. »
Ishengero ryose rimaze kubatizwa. Na Yezu nyene amaze kubatizwa, ariko arasenga, ijuru ririyugurura ; maze Mutima Mweranda aramwururukirako yibonekeje mu gisa n’inuma ; ijwi na ryo riva mw’ijuru riti : « Uri Umwananje, Jewe uyu munsi nakwivyariye. »
