Moloch was an Ammonite god.
The term Moloch is believed to have originated with the Phoenician mlk, which referred to a type of sacrifice made to confirm or acquit a vow. Melekh is the Hebrew word for “king.” It was common for the Israelites to combine the name of pagan gods with the vowels in the Hebrew word for shame: bosheth. This is how the goddess of fertility and war, Astarte, became Ashtoreth. The combination of mlk, melekh, and bosheth results in “Moloch,” which could be interpreted as “the personified ruler of shameful sacrifice.” It has also been spelled Milcom, Milkim, Malik, and Moloch. Ashtoreth was his consort, and ritual prostitution was considered an important form of worship.
Commenting on Jeremiah 7:31, Rashi stated that Moloch was made of brass; and they heated him from his lower parts; and his hands being stretched out, and made hot, they put the child between his hands, and it was burnt; when it vehemently cried out; but the priests beat a drum, that the father might not hear the voice of his son, and his heart might not be moved.
The arms of the statue had a mechanism that, when the child was put on the god’s hands, was moved by the priests, so the arms were raised to the mouth and the baby was “swallowed” by the god and fell into the fire.
The idea that the Amorites were giants is supported by the report of the spies whom Moses sent through the land of Canaan. The Amorites were one of the people groups they saw (Numbers 13:29), and they claimed that “all the people whom we saw in it are men of great stature” (Numbers 13:32). It is telling that in their response, Joshua and Caleb did not challenge the size of the land’s inhabitants (Numbers 14:6–9).
Yet it was I who destroyed the Amorite before them, whose height was like the height of the cedars, and he was as strong as the oaks; yet I destroyed his fruit above and his roots beneath. Also it was I who brought you up from the land of Egypt, and led you forty years through the wilderness, to possess the land of the Amorite (Amos 2:9–10).
The third chapter of Deuteronomy contains an interesting account of the victory of the Israelites over Sihon, the king of the Amorites, and Og, the king of Bashan. It is here that we learn an intriguing detail about Og. For only Og king of Bashan remained of the remnant of the giants [rephaim]. Indeed his bedstead was an iron bedstead. (Is it not in Rabbah of the people of Ammon?) Nine cubits is its length and four cubits its width, according to the standard cubit (Deuteronomy 3:11). With a cubit being about 1.5 feet, the Bible clearly identifies Og as a giant.
The earliest mention in Scripture of giants is just prior to the Flood account.
There were giants on the earth in those days, and also afterward, when the sons of God came in to the daughters of men and they bore children to them. Those were the mighty men who were of old, men of renown (Genesis 6:4). The word translated as “giants” in this verse is the Hebrew word nephilim.
