Having offered thyself unto God with thy whole heart and been well-pleasing unto Him, and having cleansed thy mind with ascetical labors, O God-bearer, thou wast shown to be a precious vessel of divine splendors, and dost reward each according to his sacrifice. Wherefore, celebrating thy memorial as an instructor and godly teacher, we acclaim thee in sanctity, O venerable father Isaac. Intercede with Christ God, that forgiveness of transgressions be granted to those who celebrate thy holy memory.
In that thou ineffably gavest birth in the flesh to the Savior and Fashioner of all things, O all-pure one, preserve me from the fury of the enemy, and mortify the carnal-mindedness of my flesh, directing the yearning of my soul to what is heavenly; for thou, O Theotokos, art the protection, shelter and deliverance of us who cry out to thee with faith, O pure one: Rejoice, O joy of mortals and glory of the angels, thou queen who dost ask for us, the faithful, forgiveness of offenses.

Gospel according to Matthew, §43
The Lord said to His disciples: “All things are delivered unto Me of My Father: and no man knoweth the Son, but the Father; neither knoweth any man the Father, save the Son, and he to whomsoever the Son will reveal Him. Come unto Me, all ye that labor and are heavy laden, and I will give you rest. Take My yoke upon you, and learn of Me; for I am meek and lowly in heart: and ye shall find rest unto your souls. For My yoke is easy, and My burden is light.”
After Psalm 50, this sticheron, in Tone VI—
Becoming an experienced doer of the precepts of God, thou didst truly renounce the comfort of the flesh, and didst strip thyself naked for ascetic struggles; and having restored the splendor of thy soul to the image of God, thou wast deemed worthy of manifold gifts, O venerable father Isaac; wherefore, strengthen us, that we may walk the path of virtue and become heirs to life everlasting.
