Ephesians 6:14-17 seems to have been derived and further expanded by the Apostle Paul from Isaiah 59:17. Also note that the word "salvation" in the Hebrew is Yeshuah, or Jesus as known in the western world.

Isaiah 59: 16 And He saw that there was no man, And was astonished that there was no one to intercede; Then His own arm brought salvation to Him; And His righteousness upheld Him.
17 And He put on righteousness like a breastplate, And a helmet of salvation on His head; And He put on garments of vengeance for clothing, And wrapped Himself with zeal as a mantle.
18 According to their deeds, so He will repay, Wrath to His adversaries, recompense to His enemies; To the coastlands He will make recompense.

Ephesians 6:14 Stand firm therefore, having girded your loins with truth, and having put on the breastplate of righteousness,
15 and having shod your feet with the preparation of the gospel of peace;
16 in addition to all, taking up the shield of faith with which you will be able to extinguish all the flaming missiles of the evil one.
17 And take the helmet of salvation, and the sword of the Spirit, which is the word of God.
18 With all prayer and petition pray at all times in the Spirit, and with this in view, be on the alert with all perseverance and petition for all the saints,
