From his first draft and following publication, Thackeray occasionally revised his allusions to make them more accessible for his readers. In Chapter 5, an original "Prince Whadyecallem" became "Prince Ahmed" by the 1853 edition. In Chapter 13, a passage about the filicidal Biblical figure Jephthah was removed, although references to Iphigenia remained important. In Chapter 56, Thackeray originally confused Samuel – the boy whose mother Hannah had given him up when called to by God – with Eli, the old priest to whose care he was entrusted; this mistake was not corrected until the 1889 edition, after Thackeray's death.
