Although his poems have had a prominent place in printed ritual and he is known to have lived somewhere in the Near East, documentation regarding details of the life of Eleazar ben Killir has been lost to history, including the exact year and circumstances of his birth and death.
Meskipun puisinya memiliki tempat yang menonjol dalam ritual cetak dan dia diketahui telah tinggal di suatu tempat di Timur Dekat, dokumentasi mengenai rincian kehidupan Eleazar ben Killir telah hilang dari sejarah, termasuk tahun yang tepat dan keadaan sekitar kelahiran dan kematiannya.
