found the text of oath of the night's watch:
Hear my words, and bear witness to my vow.
Night gathers, and now my watch begins. It shall not end until my death.
I shall take no wife, hold no lands, father no children.
I shall wear no crowns and win no glory.
I shall live and die at my post.
I am the sword in the darkness.
I am the watcher on the walls.
I am the shield that guards the realm of men.
I pledge my life and honor to the Night’s Watch, for this night and all the nights to come.
and one poem version of translation:
永夜终至,吾辈铭记,巍巍大任,死亦无终。
无享妻爱,不履寸土,决绝子嗣,身归兄弟。
何言无冕,兄弟所望,何争俗荣,袍泽同心。
尽忠职守,生死于斯,心念所归,无惧无退。
铸兵利剑,暗夜无当;凝聚础石,长城屹立;
腾焰熊熊,炽烈华光;耀耀破晓,璨以晨光;
鸣无尽之号角,警外患之袭扰;锻坚钢之神盾,固王国之永宁。
于今挺身,奉以生命,以夜为始,死亦无终。
