O Lord, refresh Thy flock. J. Anstice. [Passiontide.] Appeared in his posthumous Hymns, 1836, No. 27, in 5 stanzas of 4 lines, and again, with alterations, in the Child's Christian Year, 1841. In the former it is without title or heading of any kind: in the latter it is appointed for "Thursday in Passion Week." It is in several hymnbooks, the text being usually that of the Child's Christian Year.
