From the sayings of ABBA MACARIUS about Angels

While he was in the wilderness, he saw a vision; it seemed like one of the Cherubim, with wings, took his hands, ascended up to the top of the mountain and showed him all the desert, east and west, north and south. The Cherub told him, "God has given this desert to you and your sons for an inheritance."

At that time he was 30 years old, and the angel of the Lord appeared to him and walked with him for two days until they came to Wadi El-Natroun. The Saint asked the angel, "Appoint for me, O master, a place to live in." The angel replied, "I have not marked out a place for you to live, lest you leave it in the future and transgress the commandment of God. Behold all the wilderness is yours, so live wherever you wish." St. Macarius dwelt in the Inner Desert, in the place of the monastery of Saints Maximus and Domadius which is known now located by the monastery of El-Baramous.

As God saw his sincere desire for celibacy and asceticism, He sent him a Cherub, who appeared to him in a vision while he was sleeping at Wadi-el-Natroun. "God tells you," said the Cherub, "that He grants you and your (spiritual) children all this mountain, that you may devote all your time for worshipping. Many leaders will come forth in this wilderness. Awake, and remember what 1 have said; if you will live perfectly I will appear to you and declare God's words for you…” It is said that the Cherub accompanied St. Macarius all his life.
