II Corinthians 10:3-5 "For though we walk in the flesh, we do not war according to the flesh. 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,"
Ephesians 6:10-18 "Finally, my brethren, be strong in the Lord and in the power of His might. 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 host Finally, my brethren, be strong in the Lord and in the power of His might. 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 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."
Here are a few other Scripture that might help. The Father is the shield. Genesis 15:1 "After these things the word of the Lord came unto Abram in a vision, saying, Fear not, Abram: I am thy shield, and thy exceeding great reward."
This is about Jesus. Isaiah 59:16-19 "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 clock. According to their deeds, accordingly He will repay, fury to His adversaries, recompense to His enemies; the coastlands He will fully repay. So shall they fear the name of the Lord from the west, and His glory from the rising of the sun; when the enemy comes in like a flood, the Spirit of the Lord will lift up a standard against him."
As it says the sword is the word of God and the Spirit, so put on the triune God. I hope this helps.
