Metrical Apothegms in Cambridge University Library Ii.1.33, ff 224v-227v
(so no one else has to flibbert around like I just did...)
In Ker's Catalogue of Manuscripts Containing Anglo-Saxon, he mentions a "collection of metrical apothegms, moral and religious" (citing Kemble for this quote) in alliterative verse, arranged in about 20 paragraphs, in the manuscript Cambridge UL, Ii.1.33 (this is Ker's number 18 art. 44). These apothegms do not appear in volume V of the Anglo-Saxon Poetic Records, The Anglo-Saxon Minor Poems, as you might expect. They were edited, however, by James Rosier: 'Instructions for Christians,' Anglia 82 (1964): 4-22 ; 'Addenda to "Instructions for Christians",' Anglia 84 (1966): 74. The text is Dictionary of Old English Cameron number A44 (A44_Instr_T01950).
So now if you need this text, which begins "Syle ece god æhta †inra..." you can find it and won't waste forty-five flipping back and forth through the ASPR muttering "I just don't know how I missed this," before thinking to run the opening line in the DOE corpus.
