Sirach 34:26-31
{34:26} Whoever takes away the bread of sweat is like one who kills his neighbor.
{34:27} He who sheds blood, and he who cheats the hired hand out of his wages, are brothers.
{34:28} When one builds and another destroys, what benefit do they have from their labor?
{34:29} When one prays and another curses, whose voice will God heed?
{34:30} He who washes himself after touching the dead, and then touches him again, what was the benefit of his washing?
{34:31} Similarly, a man who fasts for his sins, and then does the same again, what was the benefit of his humbling himself? Who will heed his prayer?
Sirach 34:21-25
{34:21} An immolation from iniquity is a stained oblation, and the derisions of the unjust are not well pleasing.
{34:22} The Lord is only for those who persevere for him in the way of truth and justice.
{34:23} The Most High does not approve of the gifts of the iniquitous. Neither does he have respect for the oblations of the unjust; neither will he forgive their sins because of the multitude of their sacrifices.
{34:24} Whoever offers a sacrifice from the substance of the poor is like one who sacrifices the son in the sight of his father.
{34:25} The bread of the indigent is the life of the poor. Whoever cheats them out of it is a man of blood.
