When it is said
It is the hymn of the Russian Church’s prayer service for the sick, and it comes first under “Prayers for the sick” in Russian prayer books. The Orthodox Church in America prints it alone under “For the Sick”. So it is the short prayer an Orthodox Christian says at home for someone who is ill.
It is also sung in Holy Unction, a different service, in which the sick are anointed with oil. There it comes twice near the start: once before the oil is blessed, and again while it is blessed.
Where it comes from
No author known
No author, and no certain age
The service books name no author. Even its century is not known. It is in Greek service books printed in 1862 and 1872. A Russian study of Holy Unction finds it missing from most copies made from the 1300s to the 1500s. So it may be a late addition.

For one person, or for many
The Greek prays for “Your suffering servants”, in the plural. So do Russian prayer books. But in Holy Unction the Russian Church’s Slavonic prays for one “suffering servant”. The traditional English translations follow it. Anyone praying for one person says “servant” and adds the name.

“Quick” to help
In Greek the hymn opens with the word for “quick”, tachys. The Greek books set it to the tune of another hymn that opens almost the same way: “Tachy prokatalabe”, “Come quickly”. The Russian Church’s Slavonic opens “quick to defend”, not “quick to help”. So the Orthodox Church in America’s English calls Christ “our Defender”.

The Scripture in it
And the prayer offered in faith will restore the one who is sick. The Lord will raise him up. If he has sinned, he will be forgiven.
But You, O LORD, be not far off; O my Strength, come quickly to help me.
… because of the tender mercy of our God, by which the Dawn will visit us from on high …

In Greek
Ταχὺς εἰς ἀντίληψιν, μόνος ὑπάρχων Χριστέ,
ταχεῖαν τὴν ἄνωθεν, δεῖξον ἐπίσκεψιν, τοῖς πάσχουσι δούλοις Σου·
λύτρωσαι νοσημάτων, καὶ πικρῶν ἀλγηδόνων·
ἔγειρον τοῦ ὑμνεῖν Σε, καὶ δοξάζειν ἀπαύστως·
πρεσβείαις τῆς Θεοτόκου, μόνε Φιλάνθρωπε.
