THE YESHIVA
A learning community for Scripture
Yeshivat Rabban Gamaliel is a learning community dedicated to the study of the Tanakh, the New Covenant, and the roots of the faith. We seek to bridge the gap between Jewish and Messianic understanding, providing solid, verse-by-verse teaching grounded in Scripture, history, and tradition.
Founded by Rabbi Yosef Koelner, the yeshiva trains rabbis, congregational leaders, and lifelong students — online and in person — so that anyone with a hunger to understand God’s Word can learn, wherever they are.

WHO WAS RABBAN GAMALIEL?
The teacher at whose feet Paul studied
Rabban Gamaliel the Elder was a prominent Pharisee and a leading authority in the Sanhedrin — the renowned teacher under whom Saul of Tarsus, later the Apostle Paul, studied the Law in Jerusalem. Paul himself testified that he was “brought up in this city at the feet of Gamaliel, educated according to the strict manner of the law of our fathers.”
He led the School of Hillel, known for a moderate and thoughtful approach to the Law, and pioneered rulings for the good of society — protecting women, debtors, and the poor. His legacy of careful study, humility, and seeking truth is the pattern this yeshiva follows.
