Irmos: Stretching forth his arms in the form of the Cross in the belly of the sea monster, Jonah clearly prefigured the saving passion. And issuing forth after three days, he foreshadowed the transcendent resurrection of Christ God, Who was nailed in the flesh and hath enlightened the world by His rising on the third day.
Kontakion of the Cross, in Tone IV—
Bent with age and weighed down with infirmity, Jacob drew himself up when he crossed his arms, showing forth the power of the life-bearing Cross; for God Who was nailed in the flesh hath set aright the obsolescence of the law of the Scripture which was written in shadows, and hath dispelled the soul-destroying disease of deception.
Divine Israel, laying his hands cross-wise upon the heads of the young, revealed that the people who hath the honor of being the elder is a slave to the law. Wherefore, when suspected of erring in so doing, he did not alter the life-bearing image, for, he said, protected by the Cross, the newly established people of Christ God surpass them.
O Thou Who wast lifted up willingly on the Cross, bestow Thy compassions upon the new community called after Thee, O Christ God; gladden by Thy power Orthodox Christians, granting them victory over all adversaries. May they have as an ally the invincible trophy, Thy weapon of peace.
Ikos: He who was caught up to the third heaven of paradise and heard unspeakable and divine words which the human tongue cannot utter, what writeth he to the Galatians, which, as lovers of the Scriptures, ye have both read and come to understand? God forbid, saith he, that I should glory, save only in the Cross of the Lord, whereon having suffered He slew the passions. Let us all then firmly hold this boast, the Cross of the Lord; for this Wood is our salvation, the invincible trophy, the weapon of peace.
