Isomo rya 1: Yeremiya 23,5-8
Igihe kiregereje – uwo ni Uhoraho ubivuze – maze nzagoborere Dawudi umumero, umwuzukuruza w’indahemuka; azaza ari umwami ufite ubushishozi, kandi uharanira ubutabera n’ubutungane mu gihugu. Ku ngoma ye, Yuda izarokorwa, maze Israheli iture mu mutekano. Izina azitwa ni iri «Uhoraho ni we butabera bwacu.» Ni koko, igihe kiregereje -uwo ni Uhoraho ubivuze – maze boye kuzongera kuvuga ngo «Uhoraho ni Nyir’ubuzima, we wakuye Abayisraheli mu gihugu cya Misiri», ahubwo bajye bagira bati «Uhoraho ni Nyir’ubuzima, we wakuye urubyaro rw’Abayisraheli mu gihugu cyo mu majyaruguru no mu bindi byose yari yarabatatanyirijemo, kugira ngo abatuze ku butaka bwabo.»
Zaburi ya 71 (72),1-2,12-13,18-19
Mana, umwami umwegurire ubucamanza bwawe,
uwo mwana w’umwami, umutoze ubutabera bwawe;
acire umuryango wawe imanza ziboneye,
kandi arengere n’ingorwa zawe.
Azarokora ingorwa zitakamba,
n’indushyi zitagira kirengera.
Azagirira ibambe ingorwa n’utishoboye,
aramire ubuzima bwabo.
Haragasingizwa Uhoraho, Imana ya Israheli,
we wenyine ukora ibitangaza
lzina rye ry’ikuzo riragasingizwa ubuziraherezo,
ikuzo rye riragasakara ku isi hose! Amen! Amen!
Ivanjili ya Mutagatifu Matayo 1,18-24
Dore uko Yezu Kristu yavutse. Nyina Mariya yari yarasabwe na Yozefu; mu gihe batarabana, aza gusama inda ku bubasha bwa Roho Mutagatifu. Yozefu, umugabo we, wari intungane kandi utashakaga kumuteza urubwa, yigira inama yo kumusezerera rwihishwa. Igihe yari akibizirikana, Umumalayika wa Nyagasani amubonekera mu nzozi, aramubwira ati «Yozefu, mwana wa Dawudi, witinya kuzana umugeni wawe Mariya, kuko yasamye ku bubasha bwa Roho Mutagatifu. Azabyara umwana uzamwite Yezu, kuko ari we uzakiza umuryango we ibyaha byawo.» Ibyo byose ariko byabereye kugira ngo huzuzwe ibyo Nyagasani yavugishije umuhanuzi ati «Dore Umukobwa w’isugi agiye gusama inda, maze azabyare umuhungu, nuko bazamwite Emanuweli», ari byo kuvuga ngo «Imana turi kumwe.» Yozefu akangutse abigenza uko Umumalayika wa Nyagasani yamutegetse nuko azana umugeni we.
