There seems to be a lot of discussion recently about aliens and I have seen a number of people who have stated that aliens were even noted in the Bible. Here are the Bible references as they currently exist as quoted from the Amplified Bible.
Exod 18:3 And her two sons, of whom the name of the one was Gershom [expulsion, or a stranger there], for Moses said, I have been an alien in a strange land;
Deuteronomy 14:21 You shall not eat of anything that dies of itself. You may give it to the stranger or the foreigner who is within your towns that he may eat it, or you may sell it to an alien. [They are not under God’s law in this matter} but you are a people holy to the Lord your God. You shall not [even] boil a kid in its mother’s milk.
Job 19:15 Those who live temporarily in my house and my maids count me as a stranger; I am an alien in their sight.
Psalm 69:8 I have become a stranger to my brethren, and an alien to my mother’s children. [John 7:3-5.]
Proverbs 2:16 [Discretion shall watch over you, understanding shall keep you] to deliver you from the alien woman, from the outsider with her flattering words, [Prov. 2:11]
Isaiah 61:5 Aliens shall stand [ready] and feed your flocks, and foreigners shall be your plowmen and your vinedressers.
Luke 17:18 Was there no one found to return and to reognize and give thanks and praise to God except this alien?
Ephesians 2:19 Therefore you are no longer outsiders, exiles, migrants, and aliens, excluded from the rights of citizens), but you now share citizenship with the saints (God’s own people, consecrated and set apart for Himself): and you belong to God’s [own} household.
Ephesians 4:18 Their moral understanding is darkened and their reasoning is beclouded. [They are] alienated (estranged, self-banished) from the life of God [with no share in it; this is] because of the ignorance (the want of knowledge and perception, the willful blindness) that is deep-seated in them, due to their hardness of heart [to the insensitiveness of their moral nature].
Hebrews 11:34 Extinguished the power of raging fire, esaped the devourings of the sword, out of frailty and weakness won strength and became stalwart, even mighty and resistless in battle, routing alien hosts. [Dan. 3.]
Hebrews 13:9 Do not be carried about by different and varied and alien teachings; for it is good for the heart to be established and ennobled and strengthened by means of grace (God’s favor and spiritual blessing) and not [to be devoted to] foods [rules of diet and ritualistic meals], which bring no [spiritual] benefit or profit to those who observe them.
1 Peter 2:11 Beloved, I implore you as aliens and stranger and exiles [in this world] to abstain from the sensual urges (the evil desires, the passions of the flesh, your lower nature) that wage war against the soul.
1 Peter 4:12 Beloved, do not be amzed and bewildered at the fiery ordeal which is taking place to test your quality, as though something strange (unusual and alien to you and your position) were befalling you.
In each instance if you read the passage and the surrounding passages you will come to realize the term “alien” does not relate to a creature but to something strange or unfamiliar or a foreign location. It is easy to get terminology confused in the Bible as a lot of it is written in parables but in this instance each use of the term is the same or similar.
While there are obviously books that have been left out of the Bible, based on how the term is used in these passages I don’t think the inclusion of any other books will change the meaning. Feel free to do your own research. The internet while a useful tool can also contain a lot of false or misleading information.
Have a great day!
