And the tongue is a fire. 

The tongue appoints itself
to be a world of unrighteousness 
amongst parts of our body,
that pollutes the whole body

and sets on fire the circle of life
and is set on fire by Gehenna.

For every kind of both beasts and birds,
both reptiles and sea creatures
is tamed,
and has been tamed
by human kind.

But the tongue , no one from humanity can tame ,
a restless evil, 
full of deadly poison. 

With it, we bless the Lord and Father,
and with it, we curse curse humans,
who have been made in the likeness of God. 

From the same mouth comes blessings and curses.

This is not right, my brothers/sisters, these things should not be. 

Does a spring, from the same opening, pour out fresh and bitter (water)?

My brothers/sisters, a fig tree cannot bear olives, can it?
Or a grapevine figs?

A salty (spring) does not make fresh water!

Be thou my vision, O Lord of my heart;
Naught be all else to me, save that thou art –
Thou my best thought, by day or by night;
Waking or sleeping, thy presence my light.
