A Palestinian amora of the third generation (fourth century), junior contemporary of Zeira I., Ami I., and Abba (Ba) b. Mamel (Yer. Shab. 3:6a, 6:8a). Speaking of the gloriesof Solomon's Temple, he relates that when King Solomon constructed the sacred edifice he placed in it all kinds of trees made of gold; and whenever any kind of tree blossomed outside, the corresponding one inside blossomed also. In proof of this, Aḥa quotes the Biblical passage (Isaiah 35:2), "It shall blossom abundantly, and rejoice even with joy and singing: the glory of Lebanon shall be given unto it, the excellency of Carmel and Sharon." Lebanon was the symbolic name of the Temple (Yer. Yoma, 4:41d).
