Tanna of the fourth generation; a native of Kefar 'Ikos (comp. on this name H. Hildesheimer, "Beiträge zur Geographie Palästinas," pp. 12, 81, Berlin, 1886). He is mentioned almost exclusively as a transmitter of the sentences of Simeon b. Yoḥai. Two of his own exegetic sentences also have been handed down. To Exodus 14:15, "Wherefore criest thou unto me?" he says that the cry of the Israelites for aid had preceded that of Moses (Mek., Beshallaḥ, [ed. Weiss, p. 35b]). In Deuteronomy 32:6 
is to be derived from 
(= "foundation," "basis," or "means"): "He placed thee upon thy foundation" (Sifre, Deut. 309 [ed. Friedmann, p. 134a]). In another sentence of his that has been preserved mention is made of a certain place in Galilee in which were said to be leprous stones, e., stones from a house infected with leprosy (Tosef., Neg. 6:1).
