Old Testament Scriptures About Modesty
Genesis 3:21
"The Lord God made tunics of [animal] skins for Adam and his wife and clothed them."
Exodus 28:2-3
"Make sacred garments for Aaron that are glorious and beautiful. Instruct all the skilled craftsmen whom I have filled with the spirit of wisdom. Have them make garments for Aaron that will distinguish him as a priest set apart for my service."
Exodus 20:26
"And do not approach my altar by going up steps. If you do, someone might look up under your clothing and see your nakedness."
Jeremiah 13:22
"And if you [wonder] in your heart, "Why have these things happened to me?" It is because of the greatness and nature of your sin that your skirts have been pulled away [subjecting you to public disgrace] and [like a barefoot slave] your heels have been wounded."
Once again we see in this scripture that nakedness and having skirts removed is a sign of public disgrace. In the OT, we learn that nakedness being exposed is judgment for disobedience and not a fashion style.
Isaiah 47:3
"Men will see your naked body and use you for sex."
This is one of the judgments for the nation of Babylon in the Old Testament. It's similar to Genesis 3:21 about God giving Adam and Eve clothes after sin entered the world. Our naked bodies can no longer be treated with innocence and respect.
Proverbs 31:22b
"Her clothing is linen, pure and fine, and purple [wool]."
The Proverbs 31 woman dressed in splendid clothing. It's not just the material, but the spiritual implication of this scripture. Pure and fine linen means she dressed with purity, which is mentioned in Revelations 3:5 as the garments believers wear when they overcome the world.
Proverbs 7:10
"And there a woman met him dressed as a prostitute and sly and cunning of heart."
How do prostitutes dress? Revealing and appetizing to attract their customers. Any clothing that has this effect is not fit for a woman or man of God.
New Testament Scriptures About Modesty
1 Timothy 2:9
"And I want women to be modest in their appearance. They should wear decent and appropriate clothing and not draw attention to themselves by the way they fix their hair or by wearing gold or pearls or expensive clothes."
1 Peter 3:3-4
"It is not fancy hair, gold jewelry, or fine clothes that should make you beautiful. No, your beauty should come from inside you—the beauty of a gentle and quiet spirit. That beauty will never disappear. It is worth very much to God."
Galatians 5:19
"Now the practices of the sinful nature are clearly evident: they are sexual immorality, impurity, sensuality (total irresponsibility, lack of self-control),"
Romans 12:1-2
"I beseech you therefore, brethren, by the mercies of God, that ye present your bodies a living sacrifice, holy, acceptable unto God, which is your reasonable service. And be not conformed to this world: but be ye transformed by the renewing of your mind, that ye may prove what is that good, and acceptable, and perfect, will of God."
1 Corinthians 6:19-20
"You should know that your body is a temple for the Holy Spirit that you received from God and that lives in you. You don’t own yourselves. God paid a very high price to make you His. So honor God with your body."
Romans 13:13-14
"Let us conduct ourselves properly and honorably as in the [light of] day, not in carousing and drunkenness, not in sexual promiscuity and irresponsibility, not in quarreling and jealousy. But clothe yourselves with the Lord Jesus Christ, and make no provision for [nor even think about gratifying] the flesh in regard to its improper desires."
Revelation 3:5
"He who overcomes [the world through believing that Jesus is the Son of God] will accordingly be dressed in white clothing, and I will never blot out his name from the Book of Life, and I will confess and openly acknowledge his name before My Father and before His angels [saying that he is one of Mine]."
