He was born on March 17, 1647 in Stuttgart and died on April 20, 1720 in Tübingen. He became a tutor for the eldest Prince Carl Maximilian, and also for his brother Georg Friedrich in 1676, the son of Duke Eberhard III of Württemberg.
In 1680, he received the associate professorship of geography and Latin, and in 1681 the full professorship of Greek in Tübingen. In 1684, he became an instructor of practical philosophy and overseer of the Tübinger Stift. In 1702, he was appointed chancellor of the University of Tübingen.
Jäger relied on the rationalist system of natural law of Hugo Grotius.
Because of this, he helped to bring new ideas to the University of Tübingen. His work "Compendium Theologiae..pro scholis in Ducatu Wirtembergico" was introduced to Württemberg in 1702 and it replaced older textbooks of theologians such as Matthias Hafenreffer.
This work solidified orthodox doctrine by adopting Federalism and connecting closely with Biblical theology. This helped to usher in a new spirit to the faculty of the University of Tübingen.
