1 Enoch 100:5

ወዐቀብተ፡ ይሁብ፡ ዲበ፡ ኵሎሙ፡ ጻድቃን፡ ወቅዱሳን፡ እመላእክት፡ ቅዱሳን፡ ወየዐቅብዎሙ፡ ከመ፡ ብንተ፡ ዐይን፡ እስከ፡ ይትዌዳእ፡ ኵሉ፡ እከይ፡ ወኵሉ፡ ኀጢአት፡ ወእመኒ፡ ይነውሙ፡ ጻድቃን፡ ንዋመ፡ ነዋኀ፡ ይነውሙ፡ ወአልቦሙ፡ ዘይፈርሁ።

And over all the righteous and holy He will appoint guardians from amongst the holy angels To guard them as the apple of an eye, Until He makes an end of all wickedness and all sin, And though the righteous sleep a long sleep, they have nought to fear.
