or Tanna of the early post-Hadrianic period (2d cent. C.E.); a halakic exegete whose Biblical exegesis mostly belongs to the Mekilta and the Sifre. In the Tosefta he transmits sayings in the name of Eliezer ben Hyrcanus (Ter. 1:1,15; 2:5). He was a disciple of Ishmael, but associated also with the pupils of Akiba, with one of whom, named Nathan, he originated a halakah (Mek., Exodus 12:2). He was also intimate with Jonathan and with the proselyte sons of Judah in the yeshibah of Simeon ben Yoḥai (Gen. R.; M. Ḳ. 9a; Pesiḳ. 87b). Of his non-halakic exegeses may be mentioned: on Exodus 12:7: "The blood upon the doors at Passover shall serve the Egyptians as tortures for their souls" (Mek.); on Exodus 20:9: "Count the days of the week after the Sabbath" (c.); on Deuteronomy 14:11: "Unclean birds are called 
, while clean are called either 
or 
" (Sifre); on 1: "The paragraph treating of the chariot of God extends to the word 
only" (Ḥag. 13a). Another of his sayings is: "The prayer in need is adapted to all occasions" (R. H. 18a).
