Feast of the Annunciation + March 25

Verily, Gabriel did come to thee, disclosing the purpose which was before the ages, hailing thee and saying, Rejoice O unseeded land! Rejoice, O unburning bush! Rejoice, O depth inaccessible to vision! Rejoice, O bridge leading to the heavens! Rejoice, O lofty ladder whom Jacob did behold! Rejoice, O jar of divine manna! Rejoice, O dissolution of the curse! Rejoice, O recall of Adam! The Lord is with thee.

Rejoice, O Theotokos, O deliverance of Adam from the curse! Rejoice, O chaste Theotokos! Rejoice, O living bush! Rejoice, O lamp! Rejoice, O throne! Rejoice, O ladder and door! Rejoice, O divine chariot! Rejoice, O bright cloud! Rejoice, O temple, O most-gilded jar! Rejoice, O mountain! Rejoice, O tabernacle and table! Rejoice, O deliverer of Eve!
