Gamaliel IV (flourished probably late 3rd century CE;[1] also known as Gamaliel IV ben Judah II) was the son of the nasiJudah II and father of Judah III.
Hoshaiah Rabbah is said to have prevented Gamaliel from introducing into Syria a ruling referring to the tithing of crops.[3] The Jerusalem Talmud tells a story of Gamaliel's humility: Once when Abbahu asked him a question about the law, Gamaliel speaks of his own ignorance in comparison with Abbahu.[4]
