What is Moses referencing in V. 3 regarding Baal-Peor ?

  • In

Num. 25

, the Israelites engaged in sexual immorality/whoredom with Moabite women, and then they worshipped the pagan God of the Moabites, Baal of Peor/Baal-Peor. All the people who worshipped Baal were executed.

In Vv. 16-19, Moses’s examples of what not to worship are the human form, animal form, and then celestial forms. What are some practices/faiths that this command denounces?

  • Human Form:

Ancient Greek & Roman religion:

gods like Zeus, Athena, and Apollo were depicted in perfect human form; their statues were objects of devotion.

  • Egyptian religion:

Pharaohs were worshiped as divine incarnations — living gods in human form.

Emperor worship:

in ancient Rome, Japan (before WWII, the Emperor was seen as divine), and some Mesopotamian cultures, like the Assyrians & Babylonians cultures, rulers were treated as gods or divine sons.

Modern secular forms:

some ideologies or movements verge on humanism as a kind of religion, glorifying the human form, human reason, or celebrity in near-religious ways (not worship in the ritual sense, but spiritually similar in devotion). Think about how idolized celebrities are, or those who say “we’re our own gods”. This last one is the lie satan sold to Eve btw.

  • Animal Form:
  • Ancient Egyptian religion:

the Apis bull (Ptah), Anubis (jackal), Bastet (cat), Horus (falcon).

Hinduism:

many gods appear as part-animal — e.g., Ganesha (elephant-headed), Hanuman (monkey-god), Nandi (bull associated with Shiva). Cow worship here too.

Totemism:

in many indigenous traditions (Native American, African, Australian Aboriginal), certain animals are seen as sacred ancestors or spiritual guides.

Ancient Canaanite religion:

the bull was a common symbol of strength and fertility — hence the golden calf episode in

  • Exodus 32
  • Celestial Form:
  • Ancient Mesopotamian and Babylonian religion:

gods like Shamash (sun), Sin (moon), and Ishtar (Venus).

  • Aztec and Incan religion:

worship of the sun-god (e.g., Huitzilopochtli, Inti).

Astrology, horoscopes, and “stargazing” practices:

modern expressions of celestial divination, assigning influence or destiny to the positions of stars and planets — directly what verse 19 warns against (“lest you lift your eyes to heaven and bow down to them”).

New Age “spirituality”:

some strands focus on “cosmic energy,” zodiac forces, or star alignments in ways resembling ancient celestial worship. Crystal or moon rituals invoking the “energy” of the moon, planets, or elements.

Stay away from all of these, especially the horoscopes and astrology stuff, it is demonic and it is pagan worship, directly going against this command, and falls under divination, which was is an abomination to God as we read in Leviticus!

What is the gist of what Moses is saying?

Keeping in mind the Baal-Peor worship fiasco…

Moses leverages his historical recap and other historical references to call Israel to obey God. He reminds Israel of God’s judgment brought by their idolatry to Baal-Peor (24,000 died in plague) and alludes to their parents’ experience of God’s presence at Sinai when He received the Law (

Exod 19–24

). Now the punishment of wandering is over, and the inheritance of God’s promised land is imminent.

Moses warns against idolatry, and warns against worshipping the bodies of heaven, as opposed to their Creator who is in heaven.

He warns against what will happen to them when they desert God and start worshipping idols, and these warnings

do come true.

Moses finishes by asking them if any other nation has experienced what they have, to get the Israelites to realize the power of their God and that there is no other God like Him.

Again, this is a wake-up call for us. What other faith has what we have? Do the Muslims have a pure and Holy God like us? Do the pagan religions have an orderly and coherent God like us? Do the Hindus have an almighty God who is so glorious that he cannot be looked at, or do they worship cows and their dung!? We have mercy, love, order, forgiveness, and compassion in our lives, and the spiritual AND physical cleanliness of Christ.

  • Deuteronomy 8

What is Moses warning of here?

He again reminds the Israelites of what they experienced in the 40 years of wandering, and commands them to not forget the Lord their God.

When specifically does he warn about? When the Israelites are well-fed, housed well, have large amounts of cattle, silver/gold, and everything that they have is increased.

This is when he warns them to not be lifted up, i.e., prideful, and think that their wealth is from their own strength or merits. It is a call to remember God during the “good times”!

  • Deuteronomy 10

Moses is giving the essence of the Law here— how can it be summed up?

Fear, love, and obedience, particularly love. Remember, from Exodus, we looked at Christ’s words about what the greatest commandment in the Law is ‘love God with all your heart, with all your soul, and with all your mind” and “love your neighbor as yourself” (

  • Matthew 22:36-40

), because the 10 commandments boil down to those 2 things. (Week 5 Exod.)

  • CIRCUMCISE YOUR HEARTS:

What does Moses mean by "circumcise your hearts”

Moses already pointed beyond the Law, demanding inner purity; the external act of circumcision was only a shadow of baptism, as we have discussed. The “foreskin of the heart” is hardness, pride, and resistance to God; true circumcision is humility and compunction. That’s why it is said of Pharaoh that he “hardened his heart”.

That’s why St. Stephen says this of them, going to even point out that they persecuted the prophets and disobeyed the law.

V.19 says “Therefore love the stranger, for you were strangers in the land of Egypt”? Knowing what Egypt stands in for as it pertains to us Christians now, what can we interpret this as

Here is the pattern of Christian mercy: we too were strangers to God, yet He loved us; therefore we must love the stranger, i.e a non-Christian or sinner, or even someone struggling in their faith or someone who does not really practice it.

We were there once upon a time, but God still loved us. Also know that love for the stranger is love for Christ!

  • Matthew 25:35
  • Deuteronomy 13
  • FALSE PROPHETS:

What can we learn from this chapter?

To avoid false prophets, teachers, and otherwise anyone else from strays from the Orthodox (meaning true, right) faith that we have in Jesus Christ through His Church.

  • Let’s relate it to what Christ Himself says in
  • Matthew 24:23-27

, where He speaks of the end times.

It’s the same concept both ways; in the OT, “Let us go after other gods,” in the NT “Let us go after false christs”.

Pay attention to who Moses lists: false prophets, mother, children, spouse, friend, and then “inhabitants of the city”, which is to say be wary of all groups of people: false prophets/teachers, family/relatives, friends, and the public/majority. Close and near, you must be careful to protect and put your faith first always. Guard it from deception from ANYONE, no matter how beloved they are.

Bl. Theophylact

: “If the deceivers should come and say, “Christ has come, but He is hiding in the desert, or in a house within its inner chambers,” do not be deceived. For the coming of Christ needs no one to point it out, but it will be utterly clear to all, like the lightning. For just as the lightning is sudden and seen by all, so too will the Lord’s coming be visible to everyone on earth.

And as the eagles, that is, the vultures, swiftly converge on a corpse, so too all the saints, who soar in the heights, will come where Christ will be, and they will be snatched up into the clouds as the eagles. Certainly, the corpse is Christ Who died for us and lay as a corpse”.
