Truth holds everything together for a believer just as a belt holds the clothing of a soldier together. (See: [[rc://en/ta/man/translate/figs-metaphor]])

# the breastplate of righteousness
Possible meanings are 1) the gift of righteousness covers a believer's heart just as a breastplate protects the chest of a soldier or 2) our living as God wants us, gives us a clear conscience that protects our hearts the way a breastplate protects a soldier's chest.
