Ps 137:5 · Douay-Rheims
“And let them sing in the ways of the Lord: for great is the glory of the Lord.”
Patristic before A.D. 750

A.D.
Augustine of Hippo Patristic
A.D. 354–430
“"And let them sing in the paths of the Lord, that great is the glory of the Lord" [Psalm 138:5]. Let all the kings of the earth sing in the paths of the Lord. In what paths? Those that are spoken of above, "in Your mercy and Your truth." Let not then the kings of the earth be proud, let them be humble. Then let them sing in the ways of the Lord, if they be humble: let them love, and they shall sing. We know travellers that sing; they sing, and hasten to reach the end of their journey. There are evil songs, such as belong to the old man; to the new man belongs a new song. Let then the kings of the earth too walk in Your paths, let them walk and sing in Your paths. Sing what? That "great is the glory of the Lord," not of kings.”
