The righteous Joachim and Anna were childless for fifty years of their married life. In their old age the Archangel Gabriel appeared to each one of them separately, telling them that God had heard their prayers and that they would give birth to a daughter, Mary. Then St. Anna conceived by her husband and after nine months bore a daughter blessed by God and by all generations of men: the Most-holy Virgin Mary, the Theotokos.
Saints Joachim and Anna
St. Joachim was of the lineage of Judah and a descendant of King David. Anna was the daughter of Matthan the priest, from the lineage of Levi, as was Aaron the high priest. Matthan had three daughters: Mary, Sophia and Anna. Mary married, lived in Bethlehem, and gave birth to Salome; Sophia married, also lived in Bethlehem, and gave birth to Elizabeth, the mother of St. John the Forerunner; Anna married Joachim in Nazareth, and in old age gave birth to Mary, the Most-holy Theotokos. Joachim and Anna had lived together in marriage for fifty years, and yet had remained barren. They lived devoutly and quietly, and of all their income they spent one third on themselves, distributed one third to the poor and gave the other third to the Temple, and they were well provided for. Once when in their old age they came to Jerusalem to offer a sacrifice to God, the high priest Issachar reprimanded Joachim, saying: “You are not worthy that a gift be accepted from your hands, for you are childless.” Others, who had children, pushed Joachim behind them as one unworthy. This greatly grieved these two aged souls and they returned home in great sorrow. Then the two of them fell down before God in prayer, that He work a miracle with them as He once had with Abraham and Sarah, and give them a child as a comfort in their old age. Then God sent His angel, who announced to them the birth of “a daughter most-blessed, by whom all nations on earth will be blessed and through whom the salvation of the world will come.” Anna straightway conceived, and in nine month gave birth to the Holy Virgin Mary. St. Joachim lived for eighty years and Anna lived for seventy-nine, at which time they reposed in the Lord.

Apolytikion
Against all hope, the bonds of barrenness are loosed today. For, God has hearkened unto Joachim and Anna clearly promising that they would bear a godly maiden. He who commanded the angel to cry out to her, “Hail, full of grace, the Lord is with you,” will be born of her, the infinite One Himself, becoming man.
