The tithe(tenth part) was given as a
sign for the Lords portion of his people for the priesthood, but few can receive this saying because they are yet in the flesh.
Isaiah 6:13
But yet in it shall be a
tenth, and it shall
return, and shall be eaten: as a teil tree, and as an oak, whose substance is in them, when they cast their leaves: so the
holy seed shall be the substance thereof.
