Adam Clarke on 2 Kings 17:31

The Avites made Nibhaz - This was supposed to be the same as the Anubis of the Egyptians; and was in form partly of a dog, and partly of a man. A very ancient image of this kind now lies before me: it is cut out of stone, about seven inches high; has the body, legs, and arms, of a man; the head and feet of a dog; the thighs and legs covered with scales; the head crowned with a tiara; the arms crossed upon the breasts, with the fingers clenched. The figure stands upright, and the belly is very protuberant. See below.

And Tartak - This is supposed by some to be another name of the same idol; Jarchi says it was in the shape of an ass. Some think these were the representations of the sun in his chariot; Nibhaz representing the solar orb, and Tartak the chariot. See below.

Adrammelech - From אדר adar, glorious, and מלך melech, king. Probably the sun.

Anammelech - From anah, to return, and מלך melech, king. Probably, the Moloch of the Ammonites. Jarchi says, the first was in the form of a mule, the second in the form of a horse; this was probably the moon.
