Jan van Kessel the Younger's small known authentic oeuvre is different in style and execution and substantially higher in quality than the works, which have now been attributed to Pseudo Jan van Kessel the Younger.

Cornelius Van Alen Van Dyck 1846, shortly before the inauguration of the Abeih Seminary. In 1849, he was abruptly transferred from 'Abeih to Sidon, where he was expected to open a new mission station, preach, and practice medicine.

After completing the translation in 1865, he went to New York to supervise its printing, also teaching Hebrew for two years at Union Theological Seminary and studying ophthalmology. On returning to Beirut, Van Dyck became a professor of pathology and internal medicine in the medical school of the newly founded Syrian Protestant College,
