פירוש על ברכות 12:19

Wiesner, p. 18, finds here an attack on sun-worshippers (cf. fol. 7a, p. 37). Rab Huna, being a Babylonian, the Ark in his Synagogue would be in the West (see fol. 30 a, p. 197); therefore to pray with the back to the Synagogue would be praying towards the rising sun. Cf. Ezek. viii. 16.
