Tis awful  I was taught as a child in catechism  the labourer is worthy of his hire  there are four sins that cry out to heaven for justice  one of them is a oppressing the widow and orphan and the other  is defrauding the labourer of his hire  because the labourer is worthy of his hire  that's a sin that  cries to heaven for justice, that's what I was taught as a child.
