Hebrews 1:13-14 NKJV
13 But to which of the angels has He ever said:
“Sit at My right hand,
Till I make Your enemies Your footstool”?
14 Are they not all ministering spirits sent forth to minister for those who will inherit salvation?
Acts 12:5-15 NKJV
5 Peter was therefore kept in prison, but constant prayer was offered to God for him by the church. 6 And when Herod was about to bring him out, that night Peter was sleeping, bound with two chains between two soldiers; and the guards before the door were keeping the prison. 7 Now behold, an angel of the Lord stood by him, and a light shone in the prison; and he struck Peter on the side and raised him up, saying, “Arise quickly!” And his chains fell off his hands. 8 Then the angel said to him, “Gird yourself and tie on your sandals”; and so he did. And he said to him, “Put on your garment and follow me.” 9 So he went out and followed him, and did not know that what was done by the angel was real, but thought he was seeing a vision. 10 When they were past the first and the second guard posts, they came to the iron gate that leads to the city, which opened to them of its own accord; and they went out and went down one street, and immediately the angel departed from him.
11 And when Peter had come to himself, he said, “Now I know for certain that the Lord has sent His angel, and has delivered me from the hand of Herod and from all the expectation of the Jewish people.”
12 So, when he had considered this, he came to the house of Mary, the mother of John whose surname was Mark, where many were gathered together praying. 13 And as Peter knocked at the door of the gate, a girl named Rhoda came to answer. 14 When she recognized Peter’s voice, because of her gladness she did not open the gate, but ran in and announced that Peter stood before the gate. 15 But they said to her, “You are beside yourself!” Yet she kept insisting that it was so. So they said, “It is his angel.”
Matthew 18:10 NKJV
10 “Take heed that you do not despise one of these little ones, for I say to you that in heaven their angels always see the face of My Father who is in heaven.
Exodus 23:20-25 NKJV
20 “Behold, I send an Angel before you to keep you in the way and to bring you into the place which I have prepared. 21 Beware of Him and obey His voice; do not provoke Him, for He will not pardon your transgressions; for My name is in Him. 22 But if you indeed obey His voice and do all that I speak, then I will be an enemy to your enemies and an adversary to your adversaries. 23 For My Angel will go before you and bring you in to the Amorites and the Hittites and the Perizzites and the Canaanites and the Hivites and the Jebusites; and I will cut them off. 24 You shall not bow down to their gods, nor serve them, nor do according to their works; but you shall utterly overthrow them and completely break down their sacred pillars.
25 “So you shall serve the Lord your God, and He will bless your bread and your water. And I will take sickness away from the midst of you.
II Chronicles 20:21-23 NKJV
21 And when he had consulted with the people, he appointed those who should sing to the Lord, and who should praise the beauty of holiness, as they went out before the army and were saying:
“Praise the Lord,
For His mercy endures forever.”
22 Now when they began to sing and to praise, the Lord set ambushes against the people of Ammon, Moab, and Mount Seir, who had come against Judah; and they were defeated. 23 For the people of Ammon and Moab stood up against the inhabitants of Mount Seir to utterly kill and destroy them. And when they had made an end of the inhabitants of Seir, they helped to destroy one another.
