O God our Savior, the True Light, Who was baptized in the Jordan by the Prophet John, and Who did deign to enter under the roof of Zacchaeus, bringing salvation unto him and unto his house: do You, the same Lord, keep safe also from harm those [of us] who dwell herein; grant to them Your blessing, purification and bodily health, and all petitions that are unto salvation and Life everlasting; for blessed are You, as also Your Father Who is from everlasting, and Your All Holy, Good and Life creating Spirit, both now and ever, and to the ages of ages. Amen.
