Nehelamite, the
Smith's Bible Dictionary 1863
the designation of a man named Shemaiah, a false prophet, who went with the captivity to Babylon. (Jeremiah 29:24,31,32) The name is no doubt formed from that either of Shemaiah’s native place or the progenitor of his family which of the two is uncertain.
International Standard Bible Encyclopedia 1915
ne-hel'-a-mit, (ha-necheldmi): The designation of Shemaiah, a false prophet who opposed Jeremiah (Jer 29:24,31,32). The word means "dweller of Nehelam," but no such place-name is found in the Old Testament. Its etymology, however, suggests a connection with the Hebrew chalam, "to dream," and this has given rise to the rendering of the King James Version margin "dreamer."
