Armor of God

Every knight must be prepared for all blows of fate. Armed, and not only with armor, but also with the word of God.
And the text on the picture is actually here:
"Put on the full armor of God,
which God has given you so that you can stand against the wiles of the devil. Put on the armor of righteousness and take the shield of faith, with which you will be able to quench all the fiery arrows of the evil one, and take the helmet of salvation and the sword of the Spirit, which is the Word of God.

Ephesians 6:10-18
