According to the Ethiopian Orthodox Tewahedo Church canon, the birth of Our Holy Mother Virgin Maryam is celebrated on Ginbot 1 (May 9).
The parents of Our Holy Mother Virgin Mariam, Joachim and Hannah had no child even at the later stage of their lives, because Hannah was barren. The people of Israel rebuked them saying that God did not give them a child because of their sin. When Hannah the mother of Our Holy Mother prayed to have a child, she promised to God saying, "If You gives me a fruit, I will devote the child to Your Holy Temple".
One day Joachim the father of Our Holy Mother said unto Hannah his wife; "I had a dream, I saw the heavens opened, and a white bird went forth therefrom and hovered over my head". And likewise, Hanna said unto him, "I also had a dream this day, and I saw a dove sitting upon my head, and it entered into my belly."And seven days after they had told each other these things, on the seventh day of the month Nahasse Hannah conceived despite her old age. And six months after it had become known that the blessed Hannah had conceived, the family of Joachim her husband and those of her relatives heard of this. They came unto her to check what they were hearing. Now there was a certain woman among them who was blind, and she touched the belly of Hannah, saying, "Is it true, what I have heard?" Straightway her eyes were opened, and she saw the light. Then they all said, "O a child who is not yet born can heal the blind when he is born how many people he shall heal”. This matter became hard unto all the elders of Israel. From that day the elders of Israel did not see Hannah and Joachim in a good way and decided to kill them before the birth of the child. But the Angel of God, appeared unto Joachim in his dream and told him to take his wife Hannah and flee to the Mount of Lebanon.
Song of Solomon 4:8
“Come with me from Lebanon, my spouse, with me from Lebanon: look from the top of Amana, from the top of Shenir and Hermon, from the lions' dens, from the mountains of the leopards.”
Our Holy mother was born while her mother Hannah was on the journey in exile on the Mount of Lebanon. When Our Holy Mother was born, her father Joachim and her mother Hannah, were overjoyed. The place where she was born was on a mountainside hiding from the elders of Israel. All their families and relatives came to the Mount of Lebanon to see Hannah and the miracle baby. They all feast together and eat under a tree on the Mount of Lebanon and thank God for the blessed child. To commemorate this occasion in the Month of Ginbot all Ethiopian Orthodox Church believers celebrate the birth of Our Holy Mother by getting together and have a feast under a tree.
Pray for us, O Holy Virgin Maryam Mother of God.
