George Leo Haydock, on Ps 136:1

“Upon the rivers of Babylon, there we sat and wept: when we remembered Sion:”

“For Jeremias. For the time of Jeremias, and the captivity of Babylon. (Challoner) — Or “of” ( Jeremiæ. ; Haydock) Jeremias; on which subject he composed his Lamentations, as the Septuagint thus insinuate. (Worthington) — The title may be a later insertion, and is not the same in all the Greek or Latin copies. It is wholly omitted in Hebrew, &c. Theodoret blames those who have written the name of Jeremias, as he was never at Babylon. (Calmet) — He might send the psalm to the captives, (Grotius) though it were written by David, (Gerer.) who was a prophet. See Psalm lxxviii. (Berthier) — The captives express their sentiments at Babylon, (Bossuet) or at their return; (Calmet) and thus, under the figure of the earthly Jerusalem, (Berthier) aspire to heaven. (St. Augustine) — Rivers. Euphrates, &c. The Jews retired to such places to pray. (Philo, con. Flac.) (Acts xvi. 13.) (Haydock) — Sion, and all the ceremonies of religion. (Worthington)”
