Haydock's commentary

Idithun. Hebrew, "upon Idithun," was not formerly in the text. (St. Jerome)

It may be the name of an instrument, (Bellarmine) or tune, (Muis) or this master of music and Asaph might sing alternately. There is nothing certain; (Menochius) though some would hence conclude, that Asaph was the author. The occasion of the psalm is also unknown, and may be applied to all the afflicted servants of God, (Berthier) or to the captives. (Calmet)
