Irmos: Tracing an upright line with his staff, Moses divided the Red Sea for Israel, which was travelling on foot; and striking it a transverse blow, he brought the waters together over the chariots of Pharaoh, thereby inscribing the invincible weapon of the Cross. Wherefore, let us hymn Christ our God, for He hath been glorified.
Canon of the Cross, the acrostic whereof is: “Having arrayed myself in the Cross, I give utterance to hymnody”, the composition of Cosmas of Maiuma, in Tone VIII—
Of old, Moses, standing between the priests, prefigured in himself the image of Christ’s most pure sufferings; for, forming a cross with his outstretched arms, he raised up victory, vanquishing the might of the tyrant Amalek. Wherefore, let us hymn Christ our God, for He hath been glorified.
Upon a pole did Moses set the cure of the deadly and venomous sting of the serpents, and the deliverance therefrom; for to the tree, in the image of the Cross, he bound a serpent which crawleth upon the ground, triumphing over the sinister bane therein. Wherefore, let us hymn Christ God, for He hath been glorified.
The sky showed forth the victory of the Cross to the divinely wise Emperor Constantine, the pious ruler; and therein the audacity of the hostile foe was cast down, delusion was destroyed and the divine Faith spread to the ends of the earth. Wherefore let us hymn Christ our God, for He hath been glorified.
