—Biblical Data:
In the Masoretic text the name is "Molech"; in the Septuagint "Moloch." The earliest mention of Molech is in Lev. xviii. 21, where the Israelite is forbidden to sacrifice any of his children to Molech. Similarly, in Lev. xx. 2-5, it is enacted that a man who sacrifices his seed to Molech shall surely be put to death. Then, curiously, it is provided that he shall be cut off from the congregation.
In I Kings xi. 7 it is said that Solomon built a high place for Molech in the mountain "that is before Jerusalem." The same passage calls Molech an Ammonite deity. The Septuagint as quoted in the New Testament (Acts vii. 43) finds a reference to Moloch in Amos v. 26; but this is a doubtful passage. In II Kings xxiii. 10 it is stated that one of the practises to which Josiah put a stop by his reform was that of sacrificing children to Molech, and that the place where this form of worship had been practised was at Topheth, "in the valley of the children of Hinnom." This statement is confirmed by Jer. xxxii. 35. From II Kings xxi. 6 it may be inferred that this worship was introduced during the reign of Manasseh. The impression left by an uncritical reading of these passages is that Molech-worship, with its rite of child-sacrifice, was introduced from Ammon during the seventh century B.C.
Something else I saw that was interesting is apparently, Molech and Baal are the same deity though I’m not certain of that.
