Colossians 4 (KJV)

1 Masters, give unto your servants that which is just and equal; knowing that ye also have a Master in heaven.

2 Continue in prayer, and watch in the same with thanksgiving;

3 Withal praying also for us, that God would open unto us a door of utterance (a spoken word, statement, or vocal sound.), to speak the mystery of Christ, for which I am also in bonds:
4 That I may make it manifest (prominent), as I ought to speak.

5 Walk in wisdom toward them that are without, redeeming the time. Let your speech be always with grace, seasoned with salt, that ye may know how ye ought to answer every man.
