1 Enoch 9:5
3 'And now to you, the holy ones of heaven, the souls of men plead, saying, "Present our case before the Most High."' 4 And they said to the Lord of the ages: 'Lord of lords, God of gods, King of kings, and God of the ages, the throne of Your glory stands through all generations, and Your name is holy and glorious and blessed through all ages! 5 You have created all things, and over all things, You have power: all things are open and visible in Your sight, and You see all things, and nothing can hide from You. 6 You see what Azâzal has done, who has taught all unrighteousness on earth and revealed the eternal secrets that were kept in heaven, which men were eager to learn:
Hebrews 4:13
11 Thus we must make every effort to enter that rest, so that no one may fall by following the same pattern of disobedience. 12 For the word of God is living and active and sharper than any double-edged sword, piercing even to the point of dividing soul from spirit, and joints from marrow; it is able to judge the desires and thoughts of the heart. 13 And no creature is hidden from God, but everything is naked and exposed to the eyes of him to whom we must render an account. 14 Therefore since we have a great high priest who has passed through the heavens, Jesus the Son of God, let us hold fast to our confession. 15 For we do not have a high priest incapable of sympathizing with our weaknesses, but one who has been tempted in every way just as we are, yet without sin.
Notes and References
"... if these angels reside “in heaven” and are “always” in the presence of God, we must question whether they could be constantly present with the “little ones” on earth, invisibly protecting them. All the same, if they reside in heaven, then their primary function may be to watch God’s chosen, intercede for them, and perhaps request judgment against those who harm them (compare Rev 8:4; Job 5:1[LXX]; Tobit 12.12‑15; 1 Enoch 9:3; 15.2; Testament of Dan 6.1; Pseudo‑Philo L.A.B. 15.5; 1QS 2.9; Origen Stromata 5.14; 7:12; Augustine City of God 7.30; 10.25).10 Occasionally, I suppose that if God so chooses, such beings might be “sent” to assist, guide, or protect the faithful on earth. So what can we say about guardian angels? Although the term itself is not found in Scripture as such, angels do exist, but not necessarily as commonly described in popular and religious cultures. Even so, Matthew 18:10 describes angels in heaven who watch and perhaps intercede for believers. One way or another, then, God sees and knows what is happening to the faithful (see Hebrews 4:13) ..."
