Now it came to pass, as they went, that he entered into a certain village: and a certain woman named Martha received him into her house. And she had a sister called Mary, which also sat at Jesus' feet, and heard his word. But Martha was cumbered about much serving, and came to him, and said, Lord, dost thou not care that my sister hath left me to serve alone? bid her therefore that she help me. And Jesus answered and said unto her, Martha, Martha, thou art careful and troubled about many things: But one thing is needful: and Mary hath chosen that good part, which shall not be taken away from her. And it came to pass, as he spake these things, a certain woman of the company lifted up her voice, and said unto him, Blessed is the womb that bare thee, and the paps which thou hast sucked. But he said, Yea rather, blessed are they that hear the word of God, and keep it. (Luke X, 38-42, XI, 27-28)

Troparion

In giving birth thou didst preserve thy virginity; in thy dormition thou didst not forsake the world, O Theotokos. Thou wast translated unto life, since thou art the Mother of Life; and by thine intercessions dost thou deliver our souls from death.

Kontakion

The grave and death could not hold the Theotokos,
who is sleepless in her intercessions and an unfailing hope in her mediations.
For as the Mother of Life she was translated unto life by Him Who dwelt in her ever-virgin womb
