AE 600a - let not the left hand know what the right hand is doing

AE 600a
But when you do alms,
do not let the left hand know what your right hand is doing,
so that your alms may be in secret. (Matthew 6:3-4)

This signifies that good is to be done from good and for the sake of good,
and not on account of self and the world for the sake of appearance;
"alms" mean every good work;
and "let not the left hand know what that right hand is doing"
signifies that good must be done from good itself,
and not without good, since that would not be good.
The "right hand" signifies good which is a source of truth,
and the "left hand" truth from good...
these act as one in those who are in the good of love and charity,
but not as one in those who have regard to self and the world in the good they do;
therefore the"left hand" means here to know and to act without good.
"That your alms may be in secret"
signifies that it may not be fore the sake of appearance.
