Deuteronomy 4:18

18 any creature that crawls on the ground, or any fish in the waters under the earth.

Deuteronomy 4:18 Meaning and Commentary

Deuteronomy 4:18

The likeness of anything that creepeth on the ground
As serpents by many; and indeed that creature is introduced into almost all the idolatries of the Heathens, which seems to take its rise from the serpent Satan made use of to deceive our first parents:

the likeness of any fish that is in the waters beneath the earth;
as the crocodile and hippopotamus, or river horse, by the Egyptians; and Dagon and Derceto, supposed to be figures in the form of a fish, among the Phoenicians.

Deuteronomy 4:18 In-Context

16 not to act corruptly and make an idol for yourselves in the shape of any figure: a male or female form,
17 or the form of any beast on the earth, any winged creature that flies in the sky,
18 any creature that crawls on the ground, or any fish in the waters under the earth.
19 When you look to the heavens and see the sun, moon, and stars-all the array of heaven-do not be led astray to bow down and worship them. The Lord your God has provided them for all people everywhere under heaven.
20 But the Lord selected you and brought you out of Egypt's iron furnace to be a people for His inheritance, as you are today.
