Instead of one hymn, today I will share two hymns since both are so important (and I could not chose only one).
"Receive the King, O Zion. For see, He comes to thee now in meekness, to raise up Lazarus and to destroy the bitter kingdom of death. Summoned by God, let al the multitude of holy monks and laypeople assemble to save mortal men through the Passion of the Cross, and to grant in His love freedom from the passions unto all."
"O Christ, who art borne on high by the dread seraphim, as God and Creator of all, Thou dost make haste to ride on earth upon a colt, as a man like us. Bethany rejoices greatly to receive Thee, O Saviour, and Jerusalem is glad as it awaits expectantly to welcome Thee. Death has been slain, and as a foretaste of the coming Resurrection it sees Lazarus return from the dead. In joy we go to meet Thee with palms, praising the power of Thy love, O Lord"
