Beth-tappuah - The house of the apple or citron tree. Probably a place where these grew in great abundance and perfection.
Aphekah - See the note on Joshua 12:18.

And Janum,.... Under the word "Janum", Jerom writes (l), there is a village called Janua, three miles from Legion to the south, but seems not to be what is written:
and Bethtappuah is by Jerom called Bethaphu (m), and said to be a village in the tribe of Judah, fourteen miles beyond Raphia, as you go to Egypt, which is the border of Palestine:
and Aphekah; Jerom speaks (n) of a large castle in his time called Apheca, near the town of Palestine; there were several places of the name of Aphek; See Gill on Joshua 12:18. As for Bethtappuah, it seems to be a place which was dedicated to a deity to which apples were sacred, in memory of the apple by which mankind was seduced; there was in later times a goddess called Pomona from hence.
(l) De loc. Hebrews. fol. 92. I. (m) Ibid. fol. 89. F. (n) Ibid. fol. 88. D.

Janum is still unknown. Beth-tappuah has been preserved in the village of Teffuh, about two hours to the west of Hebron (Rob. ii. p. 428). Apheka has not been discovered.
