Jamieson, Fausset and Brown on Jeremiah 2:23

23. (Pr 30:12).

Baalim--plural, to express manifold excellency: compare Elohim.

see--consider.

the valley--namely, of Hinnom, or Tophet, south and east of Jerusalem: rendered infamous by the human sacrifices to Moloch in it (compare Jr 19:2, 6, 13, 14; 32:35; see on Is 30:33).

thou art--omit. The substantive that follows in this verse (and also that in Jr 2:24) is in apposition with the preceding "thou."

dromedary--rather, a "young she-camel."

traversing--literally, "enfolding"; making its ways complicated by wandering hither and thither, lusting after the male. Compare as to the Jews' spiritual lust, Ho 2:6, 7.
