Easton's Bible Dictionary (1897)
Dunghill, the modern el-Minyay, 15 miles south-south-west of Gaza (Josh. 15:31; 1 Chr. 2:49), in the south of Judah. The Pal. Mem., however, suggest Umm Deimneh, 12 miles north-east of Beersheba, as the site.
Smith's Bible Dictionary (1863)
(dunghill), one of the towns in the south district of Judah. (Joshua 15:31) In the time of Eusebius and Jerome it was called Menois, and was not far from Gaza. The first stage southward from Gaza is now el-Minyay, which is perhaps the modern representative of Menois, and therefore of Madmannah.
Hastings' Dictionary of the Bible (1898) & Schaff's Bible Dictionary
MADMAN'NAH (dunghill), a town in the South of Judah, Josh 15:31, known in the time of Eusebius and Jerome as Menois, and not far from Gaza. Wilton would identify it with el-Minyay, 15 miles from Gaza; the Pal. Memoirs suggest Umm Deimneh, 12 miles northeast of Beersheba, as its more probable site. Madmannah corresponds with Beth-marcaboth, "house of chariots," in Josh 19:5; 1 Chr 4:31.
