I heard Glenn Beck, on the radio today, saying that the "Old Testament" false god Baal was worshiped via child sacrifice (among other things). Is there any evidence of that from Tanach itself (i.e. ignoring archeological and other evidence)? I don't recall ever seeing that (not, unfortunately, that I've learned all of Tanach yet).
The prophet Jeremiah (19:5) clearly identifies the baal as one of the gods to which the Caananites offered their children:
וּבָנוּ אֶת בָּמוֹת הַבַּעַל לִשְׂרֹף אֶת בְּנֵיהֶם בָּאֵשׁ עֹלוֹת לַבָּעַל אֲשֶׁר לֹא צִוִּיתִי וְלֹא דִבַּרְתִּי וְלֹא עָלְתָה עַל לִבִּי
