These are the primary armor of God Scriptures.
After these things the word of the LORD came to Abram in a vision, saying, “Do not be afraid, Abram. I am your shield, your exceedingly great reward.”
NKJV
God's promise to Abraham is the first promise of protection in the Bible. God's presence defends His children like a shield. King David made this verse his own and repeatedly praised God as his "shield." Psalms 3:3, 5:12, 18:2, 30, 35, 28:7, 33:20, 84:11, 115:9, etc.
Put on the whole armor of God, that you may be able to stand against the wiles of the devil. For we do not wrestle against flesh and blood, but against principalities, against powers, against the rulers of the darkness of this age, against spiritual hosts of wickedness in the heavenly places. Therefore take up the whole armor of God, that you may be able to withstand in the evil day, and having done all, to stand. Stand therefore, having girded your waist with truth, having put on the breastplate of righteousness, and having shod your feet with the preparation of the gospel of peace; above all, taking the shield of faith with which you will be able to quench all the fiery darts of the wicked one. And take the helmet of salvation, and the sword of the Spirit, which is the word of God; praying always with all prayer and supplication in the Spirit, being watchful to this end with all perseverance and supplication for all the saints.
Ephesians 6:11–18
NKJV
But let us who are of the day be sober, putting on the breastplate of faith and love, and as a helmet the hope of salvation.
1 Thessalonians 5:8
NKJV
The night is far spent, the day is at hand. Therefore let us cast off the works of darkness, and let us put on the armor of light.
Romans 13:12
NKJV
For the weapons of our warfare are not carnal but mighty in God for pulling down strongholds, casting down arguments and every high thing that exalts itself against the knowledge of God, bringing every thought into captivity to the obedience of Christ, and being ready to punish all disobedience when your obedience is fulfilled.
NKJV
By the word of truth, by the power of God, by the armor of righteousness on the right hand and on the left.
NKJV
He saw that there was no man,
And wondered that there was no intercessor;
Therefore His own arm brought salvation for Him;
And His own righteousness, it sustained Him.
For He put on righteousness as a breastplate,
And a helmet of salvation on His head;
He put on the garments of vengeance for clothing,
And was clad with zeal as a cloak.
NKJV
He shall cover you with His feathers,
And under His wings you shall take refuge;
His truth shall be your shield and buckler.
NKJV
