Of angels
Thinkest thou that I cannot now pray to my Father, and he shall presently give me more than twelve legions of angels? (Matthew 26:53)
Demons
And he asked him, What is thy name? And he answered, saying, My name is Legion: for we are many. (Mark 5:9)
And they come to Jesus, and see him that was possessed with the devil, and had the legion, sitting, and clothed, and in his right mind: and they were afraid. (Mark 5:15)
